backends: Move HW cursor inhibitors to MetaBackend

Browse Source 
We are aiming for a split of HW and SW cursor rendering management.
Given the HW plane is a limited resource and the amount of cursor
renderers may be >1 (due to tablets, even though we currently use an
always-software cursor renderer there), it would ideally be able to
switch between renderers.

Being MetaCursorRenderer not really a singleton, having cursor
inhibitor accounting here doesn't pan out. Make it MetaBackend API
so all cursor renderers get the same picture.
