perf report: Add raw displaying of per-thread counters

Browse source 
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
