Add idle time laser shutdown when playing from disc based games

Add support to shut down the laser (or motor too) using debug commands on 
GameCubes when playing games from disc to avoid laser wear.

I.e: Certain disc based games will let the disc sit idle for minutes or 
potentially hours when they've fully loaded a scene. This should quietly shut 
off the laser and spin down the drive using debug commands to preserve the life 
of the laser, and then on the next read it can quickly spin it up again with 
the drive debug command.
