perf mem: Clean up perf_mem_events__ptr()

The mem_events can be retrieved from the struct perf_pmu now. An ARCH
specific perf_mem_events__ptr() is not required anymore. Remove all of
them.

The Intel hybrid has multiple mem-events-supported PMUs. But they share
the same mem_events. Other ARCHs only support one mem-events-supported
PMU. In the configuration, it's good enough to only configure the
mem_events for one PMU. Add perf_mem_events_find_pmu() which returns the
first mem-events-supported PMU.

In the perf_mem_events__init(), the perf_pmus__scan() is not required
anymore. It avoids checking the sysfs for every PMU on the system.

Make the perf_mem_events__record_args() more generic. Remove the
perf_mem_events__print_unsupport_hybrid().

Since pmu is added as a new parameter, rename perf_mem_events__ptr() to
perf_pmu__mem_events_ptr(). Several other functions also do a similar
rename.
