  [llvm-profgen] Add process filter for perf reader

For profile generation, we need to filter raw perf samples for binary of interest. Sometimes binary name along isn't enough as we can have binary of the same name running in the system. This change adds a process id filter to allow users to further disambiguiate the input raw samples.
