Improve event filters to reject earlier (#89337)

* Improve event filters to reject earlier

- Avoid running the callbacks for state added/removed from
  a domain if there are no listeners that care about the domain

- Remove some impossible checks in the listeners that will
  never match since they were already rejected by the filter

* leave one guard since there is a race when we return control via await
