cursor-renderer-native: take rotation into account

Browse Source 
Rotating an output would show duplicate cursors when the pointer is
located over an area which would be within the output if not rotated.

Make sure to swap the width/height of the output when rotated.

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/85
