Explicitly make UIManagerModule use OnBatchComplete on Android

Summary:
Currently, we scan all native modules to see if they implement the OnBatchCompleteListerner. If they do, we add those modules to a list, and when C++ calls OnBactchComplete is called, we execute the callback on each of the modules.
The only native module implementing this callback today is the UIManagerModule. With Fabric, UIManager will also not be a native module anymore. This diff removes all the work done for creating the list and assumes that UIManagerModule is the only place that is interested in OnBatchComplete call - and calls it directly.
