DO NOT MERGE Check caller for sending media key to global priority session

Prevent sending media key events from the non-system app to the global
priority session through the MediaSessionManager.dispatchMediaKeyEvent().
Note that any app can use the API indirectly with
the public API AudioManager.dispatchMediaKeyEvent().
