Summary: We use internally Qt:ScreenOrientation for representing output transforms. This is not ideal since the values do not map directly to Wayland transform values, but we can make it work by using OR combinations of Qt:ScreenOrientations. Do this for now and see if we should not better introduce an internal enum mapped directly. Additionally the OR combinations need to be handled in the drm backend at various places accordingly as well (see TODOs).
