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.

This prevents targets which include Yoga from using its private APIs.
Instances of this have been mostly cleaned up in the past diffs, with the major exception of RN Fabric. To stage this without blocking on that, I added a `yoga-private-api` target for now to keep using these headers while making it unlikely new usages will show up.

This adds a `YGErrata` bitset enum matching the API and guarantees described in https://github.com/facebook/yoga/issues/1247.
It is hooked up in later diffs. There are a couple of `YGExperimentalFeature` values that belong here, but keeping the current options means that the default `YGErrataNone` corresponds to existing default behavior, letting us stage the series of changes as:
1. Implement errata API
2. Update internal Yoga users we want to de-risk to `YGErrataClassic` or `YGErrataAll` (if setting `UseLegacyStretchBehaviour`)
3. Add new errata, changing Yoga defaults to be conformant, while letting internal apps opt into compatibility modes pending experimentation.
I also added a macro to let C++ users of Yoga perform bitwise operations on the enum without casting (already available for C users).

Summary:
This removes some unused flags which will cause Yoga to layout every tree twice, then diffing the tree, reporting whether the whole tree is different. This is too expensive to run outside of local experimentation, but we have more nuanced ways to implement the `YGNodeLayoutAffectedByQuirk` I am wanting to add.

The Yoga JNI bindings use Reflection, so we need to let ProGuard know not to strip certain annotated fields.
This is done internally using a single copy of `com.facebook.proguard.annotations` from fbandroid (sometimes), which is then repackaged externally, and published as its own whole Yoga specific package. We never actually inform the stock Gradle project of the rules for the annotations though, so apps must add these manually.
This simplifies the setup, where Yoga has its own self-contained annotations/rules. The rules are exposed for Gradle/Buck dependencies, but RN and Litho both consume Yoga via dirsync + custom Gradle logic, so we need to duplicate the proguard rules to them instead of them being propagated automatically.

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.

Summary:
In D17439957, I noted that YogaLogger#log throws a NoMethodFoundException when called from C++ b/c C++ and Java's signatures of that method don't match. C++ uses YogaNodeJNIBase for the first param, Java uses YogaNode. Both my attempts to fix this failed.
Attempt #1 - Make Java use YogaNodeJNIBase. This doesn't work because the :java-interface target includes YogaLogger but not YogaNodeJNIBase. Moving YogaLogger to the impl target doesn't work either b/c other files in :java-interface reference YogaLogger.
Attempt #2 - Make C++ use YogaNode. This doesn't work b/c we try to call the log method with objects of fbjni type YogaNodeJNIBase. This would be fine in Java since YogaNodeJNIBase extends YogaNode. But fbjni's typing isn't advanced enough to know this, so the Yoga C++ fails to compile.
At this point, I was wondering what the value of having this param in the log function at all was. None of the implementations in our codebase use it today. It might be easier to just remove it all together. This also removes a bug with YGNodePrint where we pass a null layout context that eventually causes a SIG_ABRT when we use it to try to find a YogaNode to pass to this function.
