simpleperf: Support monitoring different events on different cores
Android devices usually have big little cores, which may support
different perf events. So we may want to monitor different events
on different cores at the same time. To support it, change the --cpu
option into an ordered option. For example, we can use
`--cpu 0-3 -e raw-l3d-cache-refill-rd --cpu 4-8 -e raw-l3d-cache-refill`
to monitor raw-l3d-cache-refill-rd on cpu 0-3, and raw-l3d-cache-refill
on cpu 4-8.
