[RFC v1 2/9] drm/xe/exec_queue: Add list link for the hw engine group

[Francois Dugast]

The exec queues running on hw engines belonging to the same hw engine
group share hardware resources. It will be necessary to navigate
between exec queues within a group for synchronization, hence this
new list link.
