Add a yapf style config file.

This makes the default "google" style and will help prevent people from accidentally using the yapf default style.

Fix #2428

FWIW, we put this into CUDA-QX. Hopefully it is equivalent to what you have here?

Yes. The file being added is the output from the tool itself for the "google" style. I guess the verbose format is intended to make sure any changes to default settings in future releases of yapf don't cause all the source code to get reformatted? That's a "known" issue when using clang-format, for example.

At any rate, it's the same "google" style settings.

I suspect we should consider updating .github/workflows/repo_checks.yml, too, because it is calling yapf --style google, which would override this style file. That is - if a future release of yapf changed the default settings, that part of our CI would be unhappy with people attempting to use the yapf style file in the PR.
