Add support for Python 3.12

[inlined]

Fixes #6666

I've deployed a test application and verified that Python 3.12.1 was running. IDK where the integration tests are though, so I'll let the regular folks own quality control.

Python 3.12 is the 'recommend' runtime for Python on Cloud Run. v2 cloud functions run on Cloud Run.

FWIW, I hacked this PR into firebase-tools and saved it using a pnpm patch file. I tested deployment and execution, and everything worked fine. So far we've tested only with very simple functions.

There could of course be broader issues, such as compatibility with the Firebase Python libraries. It would be nice if someone with more knowledge could review, advise and/or merge this. We are currently developing on Python 3.12.
