perf mem: Support record for hybrid platform
Support 'perf mem record' for hybrid platform. On hybrid platform,
such as Alderlake, when executing 'perf mem record', it actually calls:
record -e {cpu_core/mem-loads-aux/,cpu_core/mem-loads,ldlat=30/}:P
-e cpu_atom/mem-loads,ldlat=30/P
-e cpu_core/mem-stores/P
-e cpu_atom/mem-stores/P
