perf tools: Introduce stat perf.data header feature
Introducing the 'stat' feature to mark a perf.data as created by the
'perf stat record' command. It contains no data.
It's needed so that the report tools (report/script) can differentiate
sampling data from counting data, because they need to be treated in a
different way.
In the future it might be used to store the version of the stat storage
system used.
