Preparation for hiding pmu_events_map as an implementation detail. While the map is passed, the table of events is all that is normally wanted. While modifying the function's types, rename pmu_events_map__find to pmu_events_table__find to match later encapsulation. Similarly rename pmu_add_cpu_aliases_map to pmu_add_cpu_aliases_table.
