gh-91181: drop support for bytes on sys.path (GH-31934) 
Support for bytes broke sometime between Python 3.2 and 3.6 and has been broken ever since. Trying to bring back supports is surprisingly difficult in the face of -b and checking for keys in sys.path_importer_cache. Since the support was broken for so long, trying to overcome the difficulty of bringing back the support has been deemed not worth it.

bpo-46246: add missing __slots__ to importlib.metadata.DeprecatedList (GH-30452) 
Confirmed with @jaraco that this indeed needs a fix.

A question that came up while I was digging into the code: I think `SelectableGroups` could similarly use `__slots__ = ()`, since its purpose seems only for convenience around `dict`, not to have attributes of its own.
