Summary: Problem: In paper, there is a handy API called `[uiManager viewForReactTag:]`. Fabric does not have this mapping. The Fabric interop layer still relies on this Paper mapping. Solution: As a workaround, re-create this mapping in the Fabric interop layer. Therefore, whenever Fabric interop layer asks a paper view manager to create a view, store a weak reference to the view in a `NSMapTable`. NSMapTable allows us to customize the strong/weak relationship. I've added a comment explaining that `RCTWeakViewHolder` only needs to be used for this special circumstance.
