[PATCH i-g-t 0/3] Add tests for per-engine-class activity

[Riana Tauro]

PMU provides two counters (engine-active-ticks, total-ticks)
to calculate engine acitivity. When querying engine busyness,
user must group these 2 counters using the perf_event
group mechanism to ensure both counters are sampled together.

Add basic IGT test to validate per-engine-class activity
