Extend the PMU counters test to validate architectural events using fixed
counters.  The core logic is largely the same, the biggest difference
being that if a fixed counter exists, its associated event is available
(the SDM doesn't explicitly state this to be true, but it's KVM's ABI and
letting software program a fixed counter that doesn't actually count would
be quite bizarre).

Note, fixed counters rely on PERF_GLOBAL_CTRL.
