perf stat: Aggregate events using evsel->stats->aggr

Add a logic to aggregate counter values to the new evsel->stats->aggr.
This is not used yet so shadow stats are not updated.  But later patch
will convert the existing code to use it.

With that, we don't need to handle AGGR_GLOBAL specially anymore.  It
can use the same logic with counts, prev_counts and aggr_counts.
