[PATCH v3 4/5] KVM: selftests: Validate more arch-events in pmu_counters_test

[Sean Christopherson <seanjc@google.com>]

From: Dapeng Mi <dapeng1.mi@linux.intel.com>

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".
