[Feature] Use guix (or nix) to repack almost everything

[clsty]

What is guix?

It's a cross-distro package manager, similar to nix (actually "guix" means nix written in guile) but easier to learn (?). Its configuration language, Guile, is a general programming language for many things, comparing to nixlang which is only suitable for nixos thingy.

What to "repack"?

As much as we can, including Arch/AUR packages and even some configuration files.

Benefit?

• Ability to deploy across almost all linux distros.
  • P.S. You are able to use guix on NixOS, or use nix on GuixOS.
• Enhance stability and flexibility. Such packaging method allows multiple versions exist at same time, which makes dreams like [Feature] Revive old configs #1059 possible.
• Accelerate installation speed once we provide pre-built packages in guix (or nix).
• A big "plus" version of [Feature] Use virtual env / Use less AUR packages #1017 .
