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

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.
