RemotePlayback: prompt() method

The prompt() method of the RemotePlayback interface prompts the user to select an available remote playback device and give permission for the current media to be played using that device.

If the user gives permission, the state will be set to connecting and the user agent will connect to the device to initiate playback.

If the user chooses to instead disconnect from the device, the state will be set to disconnected and user agent will disconnect from this device.
