perf parse-events: Wildcard legacy cache events
It is inconsistent that "perf stat -e instructions-retired" wildcard opens on all PMUs while legacy cache events like "perf stat -e L1-dcache-load-miss" do not. A behavior introduced by hybrid is that a legacy cache event like L1-dcache-load-miss should wildcard open on all hybrid PMUs. Previously hybrid would call to is_event_supported for each PMU, a failure of which results in the event not being added. This isn't done in this case as the parser should just create perf_event_attr and the later open should fail, or the counter give "<not counted>". If this wants to be avoided then the PMU can be named with the event.
