Generic element call link support (#1643)

* Remove swift-url-routing and replace it with a custom implementation. It fails parsing the fragments in app.element.io links and it doesn't bring any value
* Add handling for opening generic element call links
* Add applinks support for call.element.io
* Enable VoIP and Audio playback background modes
