[PATCH i-g-t v2 00/10] Add per-client engine utilization tests

[Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>]

Port per client engine utilization tests from i915 to xe.

v2:
- Add a test to destroy exec queue before capturing sample
- Include review comments from Lucas/Riana

Opens from v1 review

1) Documenting mapping for TEST_BUSY/TEST_TRAILING_IDLE etc to tests
- Not seeing a clean way to do this since some tests iterate over all engine and
  some over virtual engines and then some tests omit hwe/width/count params.
  Would leave it as is if acceptable.

2) Busyness > 100%
- sampling RING_TIMESTAMP before utilization values is likely leading to this
  error. Ideally RING TIMESTAMP should be sampled before 1st sample and after 2nd
  sample, but that's not feasible. It can only be one way for each sample -
  either before or after.
