Add YogaNodeProperties implementation based on ByteBuffer

Summary:
@public
Adds an implementation of `YogaNodeProperties` that accesses style and layout properties using a `ByteBuffer` rather than JNI calls.
We hope for a speed improvement.

This needs further cleanup after experimenting, e.g. to codegen the offsets.
