Subject: [PATCH 01/14] perf vendor events intel: Fix icelake cstate metrics

Apply cstate fix from:
https://github.com/intel/event-converter-for-linux-perf/
so that metrics for cstates that exist on the particular architecture
are generated. This corrects issues with metric testing.

Also correct topic of ASSISTS.ANY event.
