perf stat: Move perf_counts struct and functions into separate object
Moving 'struct perf_counts' and associated functions into separate
object, so we could remove stat.c object dependency from python build.
It makes the python code to build properly, because it fails to load due
to missing stat-shadow.c object dependency if some patches from Kan
Liang are applied.
So apply this one, then Kan's.
