perf report: Add parallelism filter
Add parallelism filter that can be used to look at specific parallelism
levels only. The format is the same as cpu lists. For example:
Only single-threaded samples: --parallelism=1
Low parallelism only: --parallelism=1-4
High parallelism only: --parallelism=64-128
