Summary:
This diffs adds a separate file YGJNIVanilla.cpp to add jni methods which uses vanilla JNI instead of FBJNI.
In this diff only one method has been added to setup the experiment boolean setup.
At the end of this diff stack , we will be able to experiment between fbjni and vanilla jni in yoga and finally get rid of fbjni which saves us around 300Kb per architecture in yoga binary size.

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.

Upgrades Yoga’s copy of *fbjni* to the latest version.
This will enable us
- to move from `finalize()` to `PhantomReference` to deallocate native memory, with the potential of making GC more efficient.
- to remove the internal dependency to *libfb,* allowing apps without an own dependency to ship less code

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.

Moving all native methods in a single class provides the benefit of not having to load native bindings eagerly when just creating config objects in the startup paths, or setting Java-only values on them.
Loading native bindings triggers additional class loads (`YogaConfig` / `YogaNode`), and can lead to problems in multi-dex scenarions.

Note that only homogeneous trees are supported, i.e. **mixing weak-ref and non-weak-ref nodes will break!**
