Add audio service listener.
AudioServiceListener implements service_manager::ServiceManagerListener to
track audio service events. It is currently used for obtaining process id of
audio service utility service, needed for memory metrics introduced in
dependant CL [1]. It will also be used in a future CL to add audio service
lifetime metrics.
