Summary: This diff adds more enforcement for consistency of `ShadowNodeMutation`s, including: * `Props` object for newly created or updated view must not be nullptr; * `oldShadowView` must describe the previous state of the view for `Update` instruction; * `ignoreDuplicateCreates` option was removed. I suspect some of the crashes we see in Fabric are caused by a violation of one of these constraints. If one of these fails in debug builds, we will get an early signal.
