Frozen modules must be added to several files in order to work properly. Before this change this had to be done manually. Here we add a tool to generate the relevant lines in those files instead. This helps us avoid mistakes and omissions.

Is this ready for review (apart from the failing test)?

Yes.

(I need to figure out why "make regen-keywords" isn't working for me locally. Something about ModuleNotFoundError('dataclasses').)

I've only gotten to frozen.c, I'll review the rest later. So far this is great, I just have a few nits about outdated comments.

Here's the rest. It's looking much better than the version I used for my "codegen" experiments!

This change is focused on cleanup, so other reviewers probably aren't necessary. The next PR (freezing some of the stdlib modules) might deserve more than one.

bpo-45019: Do some cleanup related to frozen modules. (gh-28319)

There are a few things I missed in gh-27980. This is a follow-up that will make subsequent PRs cleaner. It includes fixes to tests and tools that reference the frozen modules.
