Chris Wilson fe5a708267 drm/i915/gt: Make timeslicing an explicit engine property ...

In order to allow userspace to rely on timeslicing to reorder their
batches, we must support preemption of those user batches. Declare
timeslicing as an explicit property that is a combination of having the
kernel support and HW support.
