Adds internal helpers to YGConfig to make bit manipulation more readable. We also expose `hasErrata()` to YGNode beacuse checking that will be a common pattern. We intentionally don't add mutating functions to the node, since current model is to inval a node on commiting whole config.
This is not exposed via the C ABI.

Java bindings for Yoga rely solely on garbage collection for memory management. Each Java `YogaNode` has references to its children and parent Java Nodes. This means, for a node to be garbage collected, it cannot be reachable from any user accessible node. Each node then has single ownership of a `YGNodeRef`. When the `YogaNode` is garbage collected, a finalizer is run to call `YGNodeFree` and free the underlying native Yoga Node.
This may cause a use-after-free if finalizers are run from multiple threads. This is because `YGNodeFree` does more than just freeing, but instead also interacts with its parent and children nodes to detach itself, and remove any dangling pointers. If multiple threads run finalizers at once, one may traverse and try to mutate a node which another is freeing.
Because we know the entire connected tree is dead, there is no need to remove dangling pointers, so I want to expose a way to just free a Yoga Node, without it mutating the tree as a side effect.
This adds a currently private `YGNodeDeallocate` that frees without traversal. Ideally from naming this is what `YGNodeFree` would do, but we think changing the behavior of that might be too disruptive to OSS. At the same time there may be other memory safety related API changes we would like to eventually make, so this isn't made public beyond the JNI bindings to prevent needing to transition more APIs.

In Fabric, a ShadowNode may re-initialize YGConfig several times throughout the lifetime of a perpetually cloned Yoga Node.
RN sets `pointScaleFactor` lazily, when laying out the rootview. So right now it initializes a config to `pointScaleFactor` of 1.0, sets it, sets a new `pointScaleFactor` on the config, then repeats. This cycles the config between two `pointScaleFactor` values and will excessively dirty the node now that `YGNodeSetConfig` dirties on config change (D45505089)
This change makes it so that we retain previously used `pointScaleFactor` when cloning the Yoga nodes.

Pull Request resolved: https://github.com/facebook/yoga/pull/1274
Yoga exposes public APIs for dirtying Nodes, but will itself perform dirty marking when changing bits which invalidate layout. E.g. changing the style of a Node will invalidate it along with every parent Node.
Because config setting is newly public to the C ABI, this makes a similar change so that replacing a Node's config will dirty the tree above the node if there is a layout impacting config change (I don't think children need to be invalidated since child output shouldn't change given the same owner dimensions).
One quirk of this is that configs may be changed independently of the node. So someone could attach a config to a Node, then change the live config after the fact. The config does not currently have a back pointer to the Node, so we do not invalidate in that case of live config edits. The future work to rectify this would be to make configs immutable once created.
There are also currently some experimental features here which should maybe be compared, but these should be moved to YGErrata anyway.

Pull Request resolved: https://github.com/facebook/yoga/pull/1255
This diff wires up YGErrata to a public API, along with existing functions to set UseLegacyStretchBehaviour.
The `UseLegacyStretchBehaviour` functions will be removed after the world internally is transitioned to `YGConfigSetErrata`. This is intentionally breaking, since most users previously enabling `UseLegacyStretchBehaviour` will want to pick a new appropriate errata setting. Internally, users of the API will be moved to`YGErrataAll`.
The overall change looks like:
1. Clean up YGConfig to use accessors/setters
2. Change up YGconfig internal storage
1. Fabric has a config per ShadowNode, so it makes sense to do some size optimization before adding more (free-form bools to bitfield, `std::array<bool,>` to `std::bitset` since not specialized)
3. Wire accessor/setter of UseLegacyStretchBehaviour to errata while both APIs exist
4. Add errata APIs to C ABI
After this we will need to expose the ABI to more language projections, and (more involved), add usages of the API to internal consumption of Yoga before adding more errata and removing `UseLegacyStretchBehaviour`.
Note that this API representation is similar, but distinct to `YGExperimentalFeature`. I think that API may also have made sense as an enum bitset, like we explicitly want for the new API, but it's not really worth changing the existing API to make that happen.

2. Update internal Yoga users we want to de-risk to `YGErrataClassic` or `YGErrataAll` (if setting `UseLegacyStretchBehaviour`)

Fabric relies on the private C++ internals of Yoga. This creates a conundrum in the open source build due to how header creation in Cocoapods works.
1. The default mechanism of specifying public headers needs to include the private headers for them to be made usable by fabric (by default)
2. Cocoapods will roll up all of the public headers when importing a module
https://github.com/facebook/react-native/pull/33381 fixed the Fabric Cocoapods build which ran into this. React Native relies on FlipperKit which relies on YogaKit, which in turn finally imports the Yoga podspec. Because YogaKit may use Swift, we can only expose the public Yoga C ABI.
The first solution in that PR was to allow RN to access Yoga private headers, but this was changed to instead make all Yoga headers public, and to add ifdefs to all of them to no-op when included outside of a C++ environment.
Talking to Kudo, we should be able to change back to the earlier approach in the PR, to instead expose the private headers to only RN. This lets us avoid exposing headers that we ideally wouldn't be, and lets us avoid the messy ifdefs in every Yoga header.

D15296732 added a byte to each YGNode exposed via private API, to stash random junk in. At the time, not adding to node size because of how fields ended up aligning. I'm not sure if this is still the case, but this is subject to change (e.g. adding a single extra flag).
There is a per-node "context" already that can store arbitrary data, and this reserved space isn't public, so this API is already a bit suspect.
The only place it is used is in instrumentation in fbandroid, enabled only in benchmarks, to store an enum to forward to QPL for what framework it thinks created the Yoga Node.
This is already broken for React Native (worked for Paper only), and afaict isn't used anywhere. But it also has little reason to be caching more information on the node (beyond maybe saving a couple memory accesses) since it derives this information from the node config already.
This removes the field.

## Approach
We're using `betweenMainDim` to add [gap between](bbeede82d3/yoga/Yoga.cpp (L2495)) items in main axis. This is resulting in increased [main axis](bbeede82d3/yoga/Yoga.cpp (L2598)) dimension of the container as it gets added even for the last element. One solution is to keep using it and subtract the gap when last element is reached.
## Aside
Mutating this value feels weird, but I think `betweenMainDim` gets initialized for every line so should be fine? I did some manual tests to verify. I tried running tests but I'll have to downgrade the java version. Let me know if anything fails. Thanks! 🙏

Summary:
Yoga tries to use `std::bit_cast<>()` where it's available and falls back to
`std::memcpy()` everywhere else. Unfortunately, the feature-test macro
(`__cpp_lib_bit_cast`) is only defined if the feature is available *and you have
already included either `<version>` or `<bit>`* (or something else that includes
one of those). Since `CompactValue.h` checks `__cpp_lib_bit_cast` *first*, it's
not defined even if it *would be* defined, leading the header not to
`#include <bit>`, leaving `std::bit_cast<>()` undefined; later, other headers
from the STL are included, leading to `__cpp_lib_bit_cast` *becoming* defined
and causing later code to choose to use the undefind `std::bit_cast<>()`.
This diff fixes the problem by `#include`ing either `<version>` or `<ciso646>`
(depending on availability) before checking any feature-test macros.

Pull Request resolved: https://github.com/facebook/yoga/pull/1173
In https://github.com/facebook/react-native/issues/35351 we see incorrect child item height when the flex-wrap is enabled, the cross-axis is to be stretched, and main-axis overflow is caused by gap.
In YGDistributeFreeSpaceSecondPass, if we do not have overflow (determined by flexBasisOverflows), we have stretch cross-alignment, and we reason that nothing can add to main axis dimensions, we know we're a single line and want to take full cross dimensions. and can set YGMeasureModeExactly which uses parent dimensions. Guessing an optimization?
If we do have overflow, then we set YGMeasureModeAtMost to find minimum possible cross-axis dimensions instead.
`flexBasisOverflows` incorporates both computed flex basis, and margin, so it is more generally a flag for whether we will wrap. So we should incorporate gap spacing into it. E.g. it is also used for whether we should the match main axis parent dimension of the overall container. This change does just that, and renames the flag to `mainAxisOverflows`.
We will want to cherry-pick the fix for this into RN 0.71 since we have not yet introduced the community to the incorrect behavior, and we expect a lot of usage of flex-gap.

The core functionality in this PR looks to be well tested from the fixtures added. I am not an expert in the internals of Yoga, but I am seeing everything that I would expect to. The space for the gap is accounted for in line-breaking, and the accumulated gaps limit the available line-length, before sizing flexible children, so items are sized correctly as to accommodate the gap. Then the gap is used for spacing during main axis and cross-axis justification.

Summary:
This adds the YGGutter enum, used to choose between row/column gap variants (row-gap, column-gap, gap).
This used later in changes from https://github.com/facebook/yoga/pull/1116, in the APIs which deal with setting gap on style on yoga node.
Note the original PR called this `YGGap`, but this ending up leading to a couple public method signatures that could appear ambiguous:
1. `SetGap(YGGap gap, float gapLength)`: Enums like `YGAlign` are the vaues for an `align` prop. `YGGap` controls the variant of the gap (like `YGEdge` does for left/right/top/bottom variants). So the enum reads as if it is the `gapValue`, and it looks like we have two of the same parameter.
2. `SetGap(YGGap gapDirection, float gap)`: This is misleading, because the direction gaps flow is the cross-axis of flex-direction.
3. `GetGap(YGGap gap)`: `gap` is the variant, but looks like an out param.
The [CSS Box Alignment](https://www.w3.org/TR/css-align-3/#column-row-gap) spec refers to these gaps as "Gutters", which removes the ambiguity.

https://github.com/facebook/yoga/pull/1116 adds a new enum. The enum generator is out of date with copyright header, and some codemods, but it also looks like there were manual changes, types added, etc since generation. I fixed up the script to incorporate generating the changes folks made manually, and also added an enum that was previously only added manually to the C ABI.
