If the job about to be submitted is a dma-fence job, update the current
execution mode of the hw engine group. This triggers an immediate suspend
of the exec queues running faulting long-running jobs.
If the job about to be submitted is a long-running job, kick a new worker
used to resume the exec queues running faulting long-running jobs once
the dma-fence jobs have completed.
v2: Kick the resume worker from exec IOCTL, switch to unordered workqueue,
destroy it after use (Matt Brost)
v3: Do not resume if no exec queue was suspended (Matt Brost)
v4: Squash commits (Matt Brost)
v5: Do not kick the worker when xe_vm_in_preempt_fence_mode (Matt Brost)
