Switch async_track_state_change to the faster async_track_state_change_event part 2

[bdraco]

I'm slowly switching these over so async_track_state_change_event gets used in new code instead of async_track_state_change when possible since code tends to get copied.

Proposed change

Calling async_track_state_change_event directly is faster than async_track_state_change (see #37251) since async_track_state_change is a wrapper around async_track_state_change_event now
