drm/xe: Ban entire multi-queue group on any job timeout

drm/xe: Ban entire multi-queue group on any job timeout

In multi-queue mode, we only have control over the entire group, so we
cannot ban individual queues or signal fences until the whole group is
removed from hardware. Implement banning of the entire group if any job
within it times out.

v2:
 - Fix lock inversion (Niranjana)
 - Initialize new queues in group to stopped
v3:
 - Blindly call xe_exec_queue_multi_queue_primary (Niranjana)
 - More comments around temporary list when stopping (Niranjana)
 - Restart group on false timeout (Niranjana)
