Remove Yoga-internal.h (facebook#1452)

Summary:
X-link: facebook/react-native#41346

Pull Request resolved: facebook#1452

This removes the last remnant from `Yoga-interna.h`, `YGNodeDellocate()`. The API is renamed to `YGNodeFinalize` to give it the explicit purpose of freeing the node from a garbage collector, and made public with that documented contract.

With that, every top-level header is now a public API, and Yoga's JNI bindings do not need to rely on private headers anymore.
