perf stat: Add perf_stat_process_percore()
The perf_stat_process_percore() is to aggregate counts for an event per-core
even if the aggr_mode is AGGR_NONE. This is enabled when user requested it
on the command line.
To handle that, it keeps the per-cpu counts at first. And then it aggregates
the counts that have the same core id in the aggr->counts and updates the
values for each cpu back.
Later, per-core events will skip one of the CPUs unless percore-show-thread
option is given. In that case, it can simply print all cpu stats with the
updated (per-core) values.
