Update DialogFragment UI when BT device is add/remove/rename

Browse Source 
* Add AudioSwitchCallback() in AudioSwitchPreferenceController.
  This callback is used to notify SoudSettings to update the dialogFragment UI.
* Add UpdatableListPreferenceDialogFragment that updates the available
  options when dialog is shown
* Add test to verify the adapter count when
  onListPreferenceUpdated() is called.
