[PATCH i-g-t 0/3] Add PMU tests to validate engine activity

[Riana Tauro <riana.tauro@intel.com>]

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

Add two tests to validate engine activity

engine-activity-idle
engine-activity
