Subject: [PATCH] Fabric: Clone function for RootShadowNode

Summary:
RootShadowNode does not have ComponentDescriptor counterpart (because it cannot be created via UIManager) and we used to always clone it manually.
However, apparently, some algorithms (e.g. clone algorithm inside RootShadowNode, which is used by setNativeProps) require valid clone function associated with the node.
So, we implement it.
