perf diff: Support --cpu filter option
To improve 'perf diff', implement a --cpu filter option. Multiple CPUs can be provided as a comma-separated list with no space: 0,1. Ranges of CPUs are specified with -: 0-2. Default is to report samples on all CPUs. For example, perf diff --cpu 0,1 It only diff the samples for CPU0 and CPU1.
