perf tools: Check if mem_events is supported for hybrid platform
Check if the mem_events ('mem-loads' and 'mem-stores') exist
in the sysfs path.
For Alderlake, the hybrid cpu pmu are "cpu_core" and "cpu_atom".
Check the existing of following paths:
/sys/devices/cpu_atom/events/mem-loads
/sys/devices/cpu_atom/events/mem-stores
/sys/devices/cpu_core/events/mem-loads
/sys/devices/cpu_core/events/mem-stores
If the patch exists, the mem_event is supported.
