Add additional information to drm client so it can report the last 50 exec queues to have been banned on it, as well as the last pagefault seen when said exec queues were banned. Since we cannot reasonably associate a pagefault to a specific exec queue, we currently report the last seen pagefault on the associated hw engine instead. The last pagefault seen per exec queue is saved to the hw engine, and the pagefault is updated during the pagefault handling process in xe_gt_pagefault. The last seen pagefault is reset when the engine is reset because any future exec queue bans likely were not caused by said pagefault after the reset. Also add a tracker that counts the number of times the drm client has experienced an engine reset.
