perf report: Add latency output field

Browse Source 
Latency output field is similar to overhead, but represents overhead for
latency rather than CPU consumption. It's re-scaled from overhead by dividing
weight by the current parallelism level at the time of the sample.
It effectively models profiling with 1 sample taken per unit of wall-clock
time rather than unit of CPU time.
