Define new, perf tool only, sample types and their layouts. Add logic to parse /proc/schedstat, convert it to perf sample format and save samples to perf.data file with `perf sched stats record` command. Also add logic to read perf.data file, interpret schedstat samples and print rawdump of samples with `perf script -D`. Note that, /proc/schedstat file output is standardized with version number. The patch supports v15 but older or newer version can be added easily.
