Fixes #13574

This PR fixes the generation of type hints for static methods of pybind11 classes. The code changes are based on the suggestions in #13574.

The fix introduces an additional check if the property under inspection is of type staticmethod. If it is, the type information is read from the staticmethod's __func__ attribute, instead of the staticmethod instance itself.

I added a test for C++ classes with static methods bound using pybind11. Both, an overloaded and a non-overloaded static method are tested.

Hi @sobolevn and @AlexWaygood, please give me an update on this PR. Is there a reason why it has not been merged? As far as I can see, I can not merge it myself since I don't have the necessary permissions.

I can't merge this PR, because I don't fully understand the C++ code, but I think that @JukkaL or @msullivan can help us :)

I can't merge this PR because I'm not a maintainer

Thanks for the info :) I was under the impression that you could merge, since you were reviewing my changes. I will wait for a reply from @JukkaL and @msullivan.

In the meantime you can resolve conflicts :)

Hi everyone, I integrated my changes into the new master branch and from my perspective it is ready for merging.

I noticed, though, that the mypyc runtime tests with py39-macos seem to be unstable. Since I did not find a way to rerun tests for a commit, I added two empty dummy commits to get the pipeline to succeed. See #16420.

You can ignore the mypyc runtime test failures, since it's a known issue happening on master.

Hi @JukkaL and @msullivan, I resolved conflicts with the current master branch. Can this PR be merged?

Happy new year everyone! 🥳 Are there plans to merge this PR yet? I would really like to get this off my mind.

I can merge this PR if somebody who has more context on the relevant code than I have gives a quick thumbs up.

more context on the relevant code than I have

Or somebody who has any familiarity with the code :-)
