background_callback: Add gc collect callback

A background callback must never outlive its related object.  By
collecting the head of the linked list of background tasks, this will
not happen.

One hypothetical case where this could happen is if an MP3Decoder is
deleted while its callback to fill its buffer is scheduled.

supervisor: Add a linked list of background callbacks

In time, we should transition interrupt driven background tasks out of the
overall run_background_tasks into distinct background callbacks,
so that the number of checks that occur with each tick is reduced.
