perf report: Add raw displaying of per-thread counters
If --pretty=raw is given to perf report -T, it now displays one
line per-thread per-counter with the raw event id added.
We get:
# PID TID Name Raw Count
18608 18609 cache-misses 28e 416744
18608 18609 cache-references 28f 6456792
18608 18608 cache-misses 28e 448219
18608 18608 cache-references 28f 7270244
instead of:
# PID TID cache-misses cache-references
18608 18609 416744 6456792
18608 18608 448219 7270244
