Move to a profile-based configuration where common

This patch makes it so common configuration is now located in shared/
and each host basically just becomes a bunch of import statements.

The exception here is host-specific configuration like the `*.linus.onl`
that live inside `hosts/ahmed/`.

Specifically I have:

- moved common configuration `shared/{nixos,home-manager,nix-darwin}`.
- moved `hosts/common.nix` to `shared/nixos/common-{nix,shell}-settings.nix`.
- split `hosts/muhammed/{dev-utils,neovim}` into per-language
  configuration.

This patch was done in preparation for the arrival of a new host, which
will need to share a lot of configuration with Muhammed.
