Switch dispatcher to use async_run_hass_job (#74514)

* Switch dispatcher to use async_run_hass_job

- Since we already wrap all the callbacks in catch_log_exception
  we can use async_run_hass_job here

- The overhead of wrapping the call in a call_soon, queuing it
  and running it later usually exceeds the overhead of running
  the job itself

* fix size change during iteration

* fix out of order send

* fix missing mocking in unifi test

* Fix Legrand Home+ Control updating entities before the coordinator update had finished

* stray debug
