py-nuitka: new package

[jamessmillie]

This PR adds the Nuitka python compiler to the builtin packages in Spack

[spackbot-app]

Hi @jamessmillie! I noticed that the following package(s) don't yet have maintainers:

• py-nuitka

Are you interested in adopting any of these package(s)? If so, simply add the following to the package class:

    maintainers("jamessmillie")

If not, could you contact the developers of this package and see if they are interested? You can quickly see who has worked on a package with spack blame:

$ spack blame py-nuitka

Thank you for your help! Please don't add maintainers without their consent.

You don't have to be a Spack expert or package developer in order to be a "maintainer," it just gives us a list of users willing to review PRs or debug issues relating to this package. A package can have multiple maintainers; just add a list of GitHub handles of anyone who wants to volunteer.

FYI. Confirmed the homepage and version sha256.

This looks good.

I see https://github.com/Nuitka/Nuitka?tab=readme-ov-file#c-compiler is fairly specific about which compilers are needed on which systems. I think that these constraints are for packages that use Nuitka to build - possibly for building Nuitka itself, but not just that; if that's correct, then we don't have a great way to express that (i.e. "if I'm using Nuitka to build, then I need one of these compilers"), so I don't think there will be a way to address that quickly. It's an interesting modeling use case though.
