Allow a legacy cache event to be both, for example, "L1-dcache-load-miss" and "cpu/L1-dcache-load-miss/" by introducing a new legacy cache term type. The term type is processed in config_term_pmu, setting both the type in perf_event_attr and the config. The code to determine the config is factored out of parse_events_add_cache and shared. If the PMU doesn't support legacy events, currently just core/hybrid PMUs do, then the term is treated like a PE_NAME term - as before. If only terms are being parsed, such as for perf_pmu__new_alias, then the PE_LEGACY_CACHE token is always parsed as PE_NAME.
