perf parse-events: Support wildcards on raw events
Legacy raw events like r1a open as PERF_TYPE_RAW on non-hybrid systems
and on each hybrid PMU on hybrid systems. Rather than iterate hybrid
PMUs add a perf_pmu__supports_wildcard_numeric function that says when
a numeric event should be opened upon it. If the parsed event
specifies the type of the PMU then don't wildcard match PMUs, use the
specified PMU type.
