Update DeviceOutputListener interface

Currently, DeviceOutputListener::StopListening() must be called once for
each call to StartListening(). This means that a listener might be
stopped and restarted in cases where it didn't need to be (e.g. when
switching between listening to the "default device ID", and the "current
default output device").

This CL updates DeviceOutputListener to support replacing a listener's
current device. This allows us to elide certain calls under the hood,
which should minimize gaps in the received reference output.
