Add a script to help update to a new CTK version

[mdboom]

This is the script I used to update to a new CTK version and create #1131. I think this will be helpful going forward. Worth adding to toolshed?

Pull Request Overview

This PR adds a script to automate the process of updating cuda-python to support a new version of the CUDA Toolkit (CTK). The script streamlines the multi-step process that was previously done manually.

• Automates CTK version updates by fetching headers, updating configuration files, and running code generation
• Handles both latest and previous version updates through command-line options
• Provides clear instructions and confirmations for manual steps that still need to be performed

Looks useful! But I think it's important to have cybind in the name, maybe update_ctk_cybind.py?

This is to distinguish from cython-gen (which already has a regenerate.py script).

Hmm... I actually didn't think of cython-gen here for this one because the last time this was manually done (in #960), none of the cython-gen-generated files needed updating. But for completeness, this should probably /also/ regenerate with cython-gen (by running that regenerate.py script). That's a trickier thing to automate because it requires /installing/ the CTK, rather than just fetching headers from the web, as this does.

What do others think?

For this time around, I'll try on the colossus workstation that I have already. I think it'll take me only a few minutes.

Not sure what'll be best long term.

Moving elsewhere.
