Revert the changes to video calls and call UI

Hi so I think the new updated to the UI in voice/video calls are pretty bad, less intuitive and more of a hassle than the old one (why do i have to adjust the stream volume instead of having a quick mute button?).
Also the new overlay for games displaying participants cameras over the game played is pretty dumb, most people tab between call and game or use a second monitor to see the cameras, at least give us an easily accessible setting to turn this off.
