Revert to legacy media for Android Auto

[OxygenCobalt]

Media3 is terrible. It uses so much memory and CPU to improve convenience over usability, requires countless hacks and workarounds, destroys my service lifecycle, and turns the service structure into a rats nest of spaghetti code since I can't neatly slice functionality across the deeply coupled API. I'm going back to compat media. Shouldn't jeopardize other service changes.
