Summary:
NativeAnimatedModule registers itself as a listener on UIManagerModule, which doesn't exist in bridgeless mode. We now have an API on ReactContext to detect if we're in bridgeless mode, so let's just bail out when that's the case (for now).
In the future, we'll need a replacement for this API on FabricUIManager (or somewhere).
