Implement audio switch UI

* Implement available media devices group * Add AvailableMediaDeviceGroupController to realize UI, the user can see the all device that can be activated in this group. * ConnectedDeviceGroupController change to show the device that cannot be activated but is connected. * Refactoring the below class, implement the controller in connected_devices.xml. ConnectedDeviceGroupController.java SavedDeviceGroupController.java ConnectedDeviceDashboardFragment.java connected_devices.xml * Add AvailableMediaBluetoothDeviceUpdaterTest to verify the add/remove preference behavior when connectedStateChanged or profileAudioStateChanged * Add test that used to verify device is connected or not in BluetoothDeviceUpdaterTest. * Add test that used to verify the add/remove preference behavior when connectedStateChanged or profileAudioStateChanged in ConnectedBluetoothDeviceUpdaterTest. * Add AvailableMediaDeviceGroupControllerTest to verify bluetooth feature is supported or not and test register callback. * Add test that used to verify bluetooth feature is supported or not and test register callback in ConnectedDeviceGroupControllerTest. * Add test that used to verify bluetooth feature is supported or not and test register callback in SavedDeviceGroupControllerTest Bug: 74134939 Test: make -j40 RunSettingsRoboTests Change-Id: I54d03c2ddadc6a4be7519dd74cdbcb5055d44083
