perf mem: Clean up perf_mem_event__supported()
For some ARCHs, e.g., ARM and AMD, to get the availability of the
mem-events, perf checks the existence of a specific PMU. For the other
ARCHs, e.g., Intel and Power, perf has to check the existence of some
specific events.
The current perf only iterates the mem-events-supported PMUs. It's not
required to check the existence of a specific PMU anymore.
Rename sysfs_name to event_name, which stores the specific mem-events.
Perf only needs to check those events for the availability of the
mem-events.
Rename perf_mem_event__supported to perf_pmu__mem_events_supported.
