Subject: [kvm-unit-tests Patch 4/5] x86: pmu: Support validation for Intel PMU fixed counter 3
Intel CPUs, like Sapphire Rapids, introduces a new fixed counter
(fixed counter 3) to counter/sample topdown.slots event, but current
code still doesn't cover this new fixed counter.
So add code to validate this new fixed counter.
