perf test: Roundtrip name, don't assume 1 event per name
Opening hardware names and a legacy cache event on a hybrid PMU opens
it on each PMU. Parsing and checking indexes fails, as the parsed
index is double the expected. Avoid checking the index by just
comparing the names immediately after the parse.
This change removes hard coded hybrid logic and removes assumptions
about the expansion of an event. On hybrid the PMUs may or may not
support an event and so using a distance isn't a consistent solution.
