Implement special app access settings for MEDIA_ROUTING_CONTROL app-op.

Bug: b/307632045
Test: Pair a watch with companion app > Settings > Apps > Special app access > enter "Change Media Output" > Find the companion app > Ensure the special app access is Allowed > ensure companion app is able to call remote media routing APIs > come back to the settings > revoke the access > ensure that now companion app is NOT able to call the remote media routing APIs.
