KVM: selftests: Validate more arch-events in pmu_counters_test
Add support for 5 new architectural events (4 topdown level 1 metrics
events and LBR inserts event) that will first show up in Intel's
Clearwater Forest CPUs. Detailed info about the new events can be found
in SDM section 21.2.7 "Pre-defined Architectural Performance Events".
