Use UIManagerHelper to access EventDispatcher in ReactViewManager

Summary:
ReactViewManager uses the bridge (CatalystInstance) to access the UIManagerModule in its onClick method. This doesn't work in bridgeless mode, so I'm replacing this callsite with the new API, which uses UIManagerHelper + the reactTag to look up the appropriate UIManager (Paper or Fabric), and get the EventDispatcher from that.
