    Revert "wayland/surface: Swap 90 and 270 degree transforms"
    
    As testing of direct scanout revealed, `META_MONITOR_TRANSFORM`
    does actually match `WL_OUTPUT_TRANSFORM` enums. The fact that
    things rendered correctly with 90/270 degree values swapped
    was because other parts of the stack got the interpretation
    wrong, most notably `meta_rectangle_transform()`.
    Thus lets revert this change and fix the stack accordingly.
    
    This reverts commit 8d9bbe109b16969557672330da0d6a26adc8eae2.
