Can we remove code?

Spotted in review https://phabricator.services.mozilla.com/D14941#inline-82271

We use our own MediaEngineTabVideoSource to handle our behind-pref tab-sharing code, instead of using the upstream webrtc.org code for this. We overload the camera::BrowserEngine enum for this here [1].

At the same time, a search [2] reveals we still start code in CamerasParent based on camera::BrowserEngine.
