drm/xe/multi_queue: Add multi queue priority property
Add support for queues of a multi queue group to set
their priority within the queue group by adding property
DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE_PRIORITY.
This is the only other property supported by secondary
queues of a multi queue group, other than
DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE.
v2: Add kernel doc for enum xe_multi_queue_priority,
Add assert for priority values, fix includes and
declarations (Matt Brost)
v3: update uapi kernel-doc (Matt Brost)
v4: uapi change due to rebase
