i915/perf_pmu: Update inter-engine semaphore detection
The kernel no longer uses semaphores between engines, unless it can do
so by preempting them with timeslices. Update the semaphore-busy to only
run when we expect semaphore usage, i.e. not on bdw/bsw.
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/1939
