[LE Audio] Add LE Audio Devices in Sound Settings

- When connected to the LE Audio Device, it will display "Play XXX on
    LEAduioDeviceName" in Sound Settings.

  - When connected to the LE Audio Device, it will display the LE Audio
    device name in the "Take call on" list for you having a active call(Hands Free).

  - Remove the @Ignore annotation for all the tests and make test
    cases pass.
