Improve rflink coverage (#19596)

* some minor tests refactor
* async/await refactor
* toggle have not brightness
* test for race condition in unknown device
* test for 'no_command' and 'not_connected'
* test for race condition in unknown device
* sensor events are handled in sensor devices, RflinkDevice handle
command events
* test race conditions & bogus entity remove
* two more tests
* Test race condition for unknown components
* Test cleanup for `commands events` and `sensor events`
