drm/xe: Update GuC submission backend to run PT jobs

Browse source

PT jobs bypass GPU execution for the final step of a bind job, using the
CPU to program the required page tables. Teach the GuC submission backend
how to execute these jobs.

PT job submission is implemented in the GuC backend for simplicity. A
follow-up patch could introduce a dedicated backend for PT jobs.
