Summary:
`YGStyle` puts Yoga enums (which are signed integers by default) into bitfields: https://fburl.com/7fowlunu
Mixing signed values and bit-fields can be error-prone and it also fails to build on Windows with `clang-cl` due to `-Wbitfield-constant-conversion` warning being treated as error:
```

This diff fixes the problem by making all enums unsigned integers. This change can be problematic only if values of the enums are serialized somewhere. CC: David Aurelio

Summary:
Instead of checking whether `YG_ENABLE_EVENTS` is defined for every publish, we simply wrap the body of the `publish` function macro that delegates to the method that actually publishes the event.
This way we get
1. easier to write code where we publish events
2. more type safety when editing, enabling editors/IDEs to show errors without knowing about `YG_ENABLE_EVENTS`

# Solution
Improved from previous solution with jpap's suggestions.
2. Passing ```gDepth``` and ```gCurrentGenerationCount``` (renamed to **_depth_** and **_generationCount_** respectively) between function calls that stem from ```YGNodeCalculateLayout```.
In ```YGNodeCalculateLayout```, pass ```depth``` as value 0, to indicate the root depth.

Summary:
`/*` is the standard throughout open source code. For example, Firefox uses single /*: https://hg.mozilla.org/mozilla-central/file/21d22b2f541258d3d1cf96c7ba5ad73e96e616b5/gfx/ipc/CompositorWidgetVsyncObserver.cpp#l3
In addition, Rust considers `/**` to be a doc comment (similar to Javadoc) and having such a comment at the beginning of the file causes `rustc` to barf.
Note that some JavaScript tooling requires `/**`. This is OK since JavaScript files were not covered by the linter in the first place, but it would be good to have that tooling fixed too.

Summary:
Replace the *copy on write* vector with an atomic pointer to a linked list.
This allows to publish without locking a mutex, at the cost of the slower traversal of a linked list (a vector has better locality).
At the moment, the typical use case is to have one subscriber, meaning that the afforementioned slower traversal is not a problem.
Adding subscribers is implemented as atomic *compare and swap.*

Here, we replace it with a free function in `Yoga.cpp`.

Summary:
In order to remove the config pointer from nodes, we have to keep track of whether the node is using web defaults.
This information fits into one bit that we can place in padding (i.e. no extra memory needed).
This allows us to get rid of config usage withing `YGNode` with some exceptions:
- `iterChildrenAfterCloningIfNeeded` -- this function will simply receive the configuration, or the cloning callback.
- `setAndPropogateUseLegacyFlag` -- will be removed in D15316863
- in `YGNode::reset` -- will go away utomatically once we remove the config pointer
