Remove support for handling SPA calls within the app. (#5515)

* Remove support for handling SPA call links.

They were a stop-gap solution whilst we were building support for embedded room calling.

* Simplify ElementCallConfiguration now that there is only 1 type of call to handle.

* Remove the unused overlayModule from NavigationRoomCoordinator.
