Keep track of a context for each listener (#72702)

* Remove async_remove_listener

This avoids the ambuigity as to what happens if same callback is added multiple times.

* Keep track of a context for each listener

This allow a update coordinator to adapt what data to request on update from the backing service based on which entities are enabled.

* Clone list before calling callbacks

The callbacks can end up unregistering and modifying the dict while iterating.

* Only yield actual values

* Add a test for update context

* Factor out iteration of _listeners to helper

* Verify context is passed to coordinator

* Switch to Any as type instead of object

* Remove function which use was dropped earliers

The use was removed in 8bee25c938
