Refactor the entire configuration

With the release of the Nvidia 555 beta drivers and their improvements to
the Wayland experience I've finally decided to return to NixOS with
Hyprland again after 2 years of running Gentoo and Opensuse Tumbleweed
on X11. So this is me committing the work done so far from the last
couple of days. Future commits will be more incremental.
