xwayland: CRTC should support all rotations
If the Wayland compositor sets a rotation on the output, Xwayland translates the transformation as an xrandr rotation for the given output. However, if the rotation is not supported by the CRTC, this is not a valid setup and xrandr queries will fail. Pretend we support all rotations and reflections so that the configuration remains a valid xrandr setup.
