feat(mobile): add cast support (#18341)
* initial cast framework complete and mocked cast dialog working

* wip casting

* casting works!

just need to add session key check and remote video controls

* cleanup of classes

* add session expiration checks

* cast dialog now shows connected device at top of list with a list header. Discovered devices are also cached for app session.

* cast video player finalized

* show fullsize assets on casting

* translation already happens on the text element

* remove prints

* fix lintings

* code review changes from @shenlong-tanwen

* fix connect method override

* fix alphabetization

* remove important

* filter chromecast audio devices

* fix some disconnect command ordering issues and unawaited futures

* remove prints

* only disconnect if we are connected

* don't try to reconnect if its the current device

* add cast button to top bar

* format sessions api

* more formatting issues fixed

* add snack bar to tell user that we cannot cast an asset that is not uploaded to server

* make casting icon change to primary color when casting is active

* only show casting snackbar if we are casting

* dont show cast button if asset is remote and we are not casting

* stop playing media if we seek to an asset that is not remote

* remove https check since it works with local http IP addresses

* remove unneeded imports

* fix recasting when socket closes

* fix info plist formatting

* only show cast button if there is an active websocket connection (ie the server is accessible)

* add device capability bitmask checks

* small comment about bitmask
