This is a newer abstraction in micropython; it'll for instance allow background tasks to be checked once per ms in the internal select module modselect. Because `MICROPY_INTERNAL_EVENT_HOOK` is used in a few locations, our own CIRCUITPY-CHANGE call to `RUN_BACKGROUND_TASKS` can be nixed. Specifically, `mp_event_handle_nowait` calls `MICROPY_INTERNAL_EVENT_HOOK` so paths from it don't need `RUN_BACKGROUND_TASKS` anymore.

I will be doing a MicroPython merge soon so I think I will wait on this a bit. |
Can we finish this now since the merges are complete? |
