Make sure XFixes invisible cursor gets freed on server reset

This uses the same hack that dix uses for the rootCursor -- allocate
a resource ID for the invisible cursor so that it gets freed at reset
time. This also allows us to unconditionally create it during
extension initialization; necessary as the privates layout may well be
different on subsequent generations.
