Overall, I don't feel strong about having new classes in `ProfileSummaryInfo.h` or in new files. Actually I once thought about the former and hesitated between the two.

I ended up with the latter mainly because PSI is included in multiple cpp files, and the new classes don't need to be included as much.

As the static data partitioning work is under development and symbolized data access profiles may need helper functions and libraries, I think we can keep it this way and do refactors later where they fit. What do you think about this?
