Move YGSetUsedCachedEntries to internal header

Summary:
@public

In order to get out of pre-releases again, we move `YGSetUsedCachedEntries` from `Yoga.h` to `Yoga-internal.h`.
This way, it’s obvious that the function is not public, and we can remove it from future versions without breaking semver contracts.
