  [profdata] Use --hot-func-list to show all hot functions (#149428)

The `--hot-func-list` flag is used for sample profiles to dump the list
of hot functions. Add support to dump hot functions for IRPGO profiles
as well.

This also removes a `priority_queue` used for `--topn`. We can instead
store all functions and sort at the end before dumping. Since we are
storing `StringRef`s, I believe this won't consume too much memory.
