drm/xe/multi_queue: Handle tearing down of a multi queue

As all queues of a multi queue group use the primary queue of the group
to interface with GuC. Hence there is a dependency between the queues of
the group. So, when primary queue of a multi queue group is cleaned up,
also trigger a cleanup of the secondary queues also. During cleanup, stop
and re-start submission for all queues of a multi queue group to avoid
any submission happening in parallel when a queue is being cleaned up.

v2: Initialize group->list_lock, add fs_reclaim dependency, remove
    unwanted secondary queues cleanup (Matt Brost)
v3: Properly handle cleanup of multi-queue group (Matt Brost)
v4: Fix IS_ENABLED(CONFIG_LOCKDEP) check (Matt Brost)
    Revert stopping/restarting of submissions on queues of the
    group in TDR as it is not needed.
