drm/xe: Split lrc seqno fence creation up
Since sometimes a lock is required to initialize a seqno fence, and it might be desirable not to hold that lock while performing memory allocations, split the lrc seqno fence creation up into an allocation phase and an initialization phase. Since lrc seqno fences under the hood are hw_fences, do the same for these and remove the xe_hw_fence_create() function since it is not used anymore.
