[1/n] Turn on camera compat mode for fixed orientation freeform activities when using camera.

Camera compat mode letterboxes camera activities that are likely to be untested on large screens and likely to be broken (fixed-orientation activities). If activated, camera compat mode will cause the camera to rotate and crop the preview to portrait if the camera feed is landscape, and changes camera and display rotation signals to match the natural orientation portrait (future changes).
