cursor-renderer/native: Replace HW cursor with KMS cursor manager

Browse Source 
This removes the old hardware cursor management code and outsources it
to MetaKmsCursorManager. What the native cursor renderer still does,
however, is the preprocessing i.e. rotating/scaling cursor that wouldn't
otherwise be fit for a cursor plane.

The cursor DRM buffers are instead of being per cursor sprite now per
CRTC, meaning we don't need to stop doing hardware cursors if part of
the cursor is on an output that doesn't support it. This is why the
whole scale/transform code changed from being per GPU to per CRTC.
