perf print-events: Print legacy cache events for each PMU

Mirroring parse_events_add_cache, list the legacy name alongside its
alias with the PMU. Remove the now unnecessary hybrid logic.

Note, the alias output removes the event type descriptor, so:
  L1-dcache-loads                                    [Hardware cache event]
becomes:
  L1-dcache-loads OR cpu/L1-dcache-loads/
