perf pmu-events: Reduce processed events by passing PMU
Pass the PMU to pmu_events_table__for_each_event so that entries that
don't match don't need to be processed by callback.
If a NULL PMU is passed then all PMUs are processed.
'perf bench internals pmu-scan's "Average PMU scanning" performance is
reduced by about 5% on an Intel tigerlake.
