drm/xe: Convert multiple bind ops into single job

This aligns with the uAPI of an array of binds or single bind that
results in multiple GPUVA ops to be considered a single atomic
operations.

The design is roughly:
- xe_vma_ops is a list of xe_vma_op (GPUVA op)
- each xe_vma_op resolves to 0-3 PT ops
- xe_vma_ops creates a single job
- if at any point during binding a failure occurs, xe_vma_ops contains
  the information necessary unwind the PT and VMA (GPUVA) state

v2:
 - add missing dma-resv slot reservation (CI, testing)
v4:
 - Fix TLB invalidation (Paulo)
 - Add missing xe_sched_job_last_fence_add/test_dep check (Inspection)
v5:
 - Invert i, j usage (Matthew Auld)
 - Add helper to test and add job dep (Matthew Auld)
 - Return on anything but -ETIME for cpu bind (Matthew Auld)
 - Return -ENOBUFS if suballoc of BB fails due to size (Matthew Auld)
 - s/do/Do (Matthew Auld)
 - Add missing comma (Matthew Auld)
 - Do not assign return value to xe_range_fence_insert (Matthew Auld)
v6:
 - s/0x1ff/MAX_PTE_PER_SDI (Matthew Auld, CI)
 - Check to large of SA in Xe to avoid triggering WARN (Matthew Auld)
 - Fix checkpatch issues
v7:
 - Rebase
 - Support more than 510 PTEs updates in a bind job (Paulo, mesa testing)
v8:
 - Rebase
