perf: Make common SAMPLE_EVENT parser
Currently, sample event data is parsed for each commands, and it is assuming that the data is not including other data. (E.g. timechart, trace, etc. can't parse the event if it has PERF_SAMPLE_CALLCHAIN) So, even if we record the superset data for multiple commands at a time, commands can't parse. etc. To fix it, this makes common sample event parser, and use it to parse sample event correctly. (PERF_SAMPLE_READ is unsupported for now though, it seems to be not using.)
