Add a runner that uses distutils/setuptools’ APIs to build extensions

This would serve as a drop-in replacement for certain use cases, but I’m not sure if it’s even tractable. If it is, it might make sense to show how, at least.

I’m mostly filing this as a “hey, have you thought about this?”. :)

That's out of scope. This is purely for things that can build extensions to define their logic and communicate where files are/should be distributed.

I think you could build something like that that uses extensionlib, the problem is Setuptools doesn't really make the logic easy to access standalone.
