[WIP] New packages: guile3, guix
https://github.com/void-linux/void-packages/pull/22359

Description:
Supersedes #22304 

- Added 3 as suffix for the guile3 executables.
- Update aisleriot, switch to guile3.
- Added dependencies for guix. I think there may be better ways of packaging them, but I'm not entirely sure. I have to fix the fact that they depend (for runtime) on the `-devel` version of other libraries, too.
- Package guix. Still needs a service file for `guix-daemon`.
