drm/xe: Add exec_queue.sched_props.job_timeout_ms
[ Upstream commit 6ae24344e2e3e12e06f7b382af4bba2fd417b2ff ]
The purpose here is to allow to optimize exec_queue_set_job_timeout()
in follow-on patch. Currently it does q->ops->set_job_timeout(...).
But we'd like to apply exec_queue_user_extensions much earlier and
q->ops cannot be called before __xe_exec_queue_init().
It will be much more efficient to instead only have to set
q->sched_props.job_timeout_ms when applying user extensions. That value
will then be used during q->ops->init().
