Support IL2CPP and fix stale handle

Browse Source 
Summary:
- Unity IL2CPP (ENABLE_IL2CPP) requires the same code path with AOT compile.
- Clean up unneeded code in YGConfigHandle.
- YogaNode.Reset makes YGNodeHandle stale. Unmanaged side was reset by YGNodeReset, but YGNodeHandle keeps to retain the old managed handle. Release it.
Closes https://github.com/facebook/yoga/pull/491
