[i-g-t 0/3] tests/xe: Add IGT coverage for SVM madvise autoreset on unmap.

[Arvind Yadav <arvind.yadav@intel.com>]

Cover full and partial unmap cases for both CPU-only and GPU-touched
VMAs, and verify that only unmapped regions are reset to default
attributes.

Test cases:

  1. multi-region-partial-unmap-no-gpu
     Set PAT=UC on 10 x 1MB VMAs, unmap 3 non-sequential regions
     without GPU access and verify remaining mapped regions retain PAT=UC.

  2. single-vma-full-unmap-no-gpu
     Set PAT=UC on a 1MB VMA, fully unmap it without GPU access, and
     verify the attribute resets to default.

  3. multi-region-partial-unmap
     Run GPU workload on all regions, then unmap 3 non-sequential
     regions and verify remaining mapped regions retain PAT=UC.
