Change the title when in call/media state

* For fix the "Automatic merge failed" in pi-dev, cherry pick the ag/3909960 in
  master. Change android.support.* to androidx.*
* Change the title when in call/media state.
  Example: call state show "Available call devices"
           media state show "Available media devices"
* Use isAudioModeOngoingCall() utility function for checking if it is in call status
* Add register test to verify when in onStart() and onStop()
  the BluetoothCallback can be register and unregister.
* Add title string test to verify when in call or media state,
  the title can be changed to corresponding string
