Summary:
This diff refactors the cloning mechanism for YogaNode used from Fabric UI renderer and RN iOS graphs.
Previously, we were cleaning the owner of the child's cloned node inside the C++ implementation of YogaNode. This was a mistake because this modified the last commited YogaTree, causing side effect in RN iOS graphs.
