perf stat record: Write stat round events on record
Writing stat round events on 'perf stat record' for each interval round.
In non interval mode we store round event after the last stat event.
Committer note:
After the patch:
$ perf report -D | grep PERF_RECORD | grep ROUND
0x852 [0x18]: PERF_RECORD_STAT_ROUND
