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.
