perf mem: Add mem_events into the supported perf_pmu
With the mem_events, perf doesn't need to read sysfs for each PMU to
find the mem-events-supported PMU. The patch also makes it possible to
clean up the related __weak functions later.
The patch is only to add the mem_events into the perf_pmu for all ARCHs.
It will be used in the later cleanup patches.
