drivers/perf: apple_m1: add known PMU events

This patch adds known PMU events that can be found on /usr/share/kpep in
macOS. The m1_pmu_events and m1_pmu_event_affinity are generated from
the script [1], which consumes the plist file from Apple. And then added
these events to m1_pmu_perf_map and m1_pmu_event_attrs with Apple's
documentation [2].
