drm/xe: Drop xe_gt_tlb_invalidation_wait

Having two methods to wait on GT TLB invalidations is not ideal. Remove
xe_gt_tlb_invalidation_wait and only use GT TLB invalidation fences.

In addition to two methods being less than ideal, once GT TLB
invalidations are coalesced the seqno cannot be assigned during
xe_gt_tlb_invalidation_ggtt/range. Thus xe_gt_tlb_invalidation_wait
would not have a seqno to wait one. A fence however can be armed and
later signaled.

v3:
 - Add explaination about coalescing to commit message
v4:
 - Don't put dma fence if defined on stack (CI)
v5:
 - Initialize ret to zero (CI)
v6:
 - Use invalidation_fence_signal helper in tlb timeout (Matthew Auld)
