window: Trap X11 warp pointer errors on MetaBackendX11

Browse Source 
Only the X11 backend cares about trapping X11 errors when
warping pointers, and there is no reason for it to be done
by MetaWindow.

Move the push()/pop() calls to MetaBackendX11, and simplify
warp_grab_pointer() by removing the boolean return value
that is not being used anywhere.
