216: Move host and suite implementation logic to lib r=nrdxp a=Pacman99

This is just the `mkSuites` and `mkHosts` part of the `mkDevos` PR. I would like to avoid changing mkSuites and mkHosts api, to make it easier to rebase changes into the mkDevos branch. But if necessary we can change them. And to that end, there is some more logic added to the flake.nix now which would ideally not be there if devos was meant to be a template. But since the goal is to move towards a lib function with template, this is just a step in that direction.
