drm/xe: Move engine masks into IP descriptor structures

Browse source

Break the top-level platform_engine_mask field into separate
hw_engine_mask fields in the graphics and media structures.  Since
hardware has more flexibility to mix-and-match IP versions going
forward, this allows each IP to list exactly which engines it provides;
the final per-GT engine list can then be constructured from those:

 * On platforms without a standalone media GT (i.e., media IP versions
   prior to 13), the primary GT's engine list is the union of the
   graphics IP's engine list and the media IP's engine list.
 * Otherwise, GT0's engine list is the graphics IP's engine list.
 * For GT1 and beyond, the type of GT determines which IP's engine list
   is used.
