perf stat: Add extra output of counter values with -vv



Add debug output of raw counter values per CPU when perf stat -v is
specified, together with their cpu numbers.  This is very useful to
debug problems with per core counters, where we can normally only see
aggregated values.

v2: Make it depend on -vv, not -v
