Element Call SPA integration (#1283)

* Integrate Element Call into EX, being able to open its URLs and handle the call in-app.
* Add custom scheme support with format `element:call?url=...`.
* Update androix.webkit
* Silence the foreground service notification.
- Allow foreground service tap action to re-open the ongoing call.
- Unify notification small icons in different modules using a vector one.
