Switches the last consumers of it to a simpler utility function that uses `pkgutil.find_loader()`: https://docs.python.org/3/library/pkgutil.html#pkgutil.find_loader Both of these consumers are covered by existing tests. Then removes `sp-grep` and the remaining parts of `pip-pop`. Closes @W-8208817@.
