Add audio switch UI in sound settings
- Build two controller to control list preferences.
- MediaOutputPreferenceController which allows switching
the media output between current device and connected
BT device supporting A2DP. It also controls disabling
media output switching during a call or cast mode.
- HandsFreeProfilePreferenceController which allows
switching between HFP-connected BT devices while in
on-call state.
- Add test cases for controllers.
