Migrate Argument Clinic docs from the CPython repo to the devguide

[erlend-aasland]

See topic on Discourse and python/cpython#107518

Prerequisites:

• Where should clinic.rst live?
• Which section (and sub-section) should the Argument Clinic docs live in? (Advanced Tools? CPython Internals?)
• Prepare devguide; rename Advanced Tools to Development Tools, and move it between Testing and Buildbots and Core Developers

Perhaps the Development Workflow is a good fit. It already contains a section about writing extension modules (although that's just a collection of links).

I really struggled with that too when you first posed the issue of moving it; of the plausible candidates:

• Development Workflow is the most crowded and is mostly focused on how to change different things rather than technical guides to specific tools, and currently has a clear and carefully thought out progression from giving an overview of CPython's development workflow and cycle to discussing how to make progressively larger and less common changes (from stdlib tweaks to porting to a whole new platform). Its not obvious where Argument Clinic would fit there (except at the end, but it still seems a little out of place).
• CPython's Internals is mostly focused on explanation type content of how and why different parts of CPython work the way they do, rather than how-to guides on how to develop CPython or use specific tools, so doesn't seem like a good fit.
• Advanced Tools is another option to consider, as it specifically covers how to use various tools for CPython development, so is at least nominally the most on-topic. It currently mostly focused on "advanced" tools (like GDB, Clang dynamic analysis, and Coverity) that won't be used by most CPython developers, so folks might not think to look there first. However, a rename to "Development Tools", a move to between Testing and Buildbots and Core Developers, and putting the Argument Clinic guide in the section first might help address that, as well as be a good spot for similar such guides in the future.

Therefore, my preference would be for Development Tools (Advanced Tools) with the changes suggested above.

Development Tools sounds good to me!
