Restore "view" argument for notification remote view click handler

The "view" argument of NotificationRemoteInputManager.Callaback#
handleRemoteViewClick had been removed by ag/4863109, because
this was unused on Android.

But we ARC wants to restore and use it to distinguish the view
issuing a click event.
