Audio cleanup (#5618)

* add different logging level callbacks for task exception logging

* Add callback to tasks which didn't have them

* The boring stuff - (apply .trace() and .verbose() to audio, stop using debug_exc_log, delete audio_logging.py)

* Unsured import cleanup

* use new lavalink method

* return so it doesn't log this twice.

* improve logging on main event handler
