modules/core: Add a new module for lazy packages
This allows to add packages to vuizvui.lazyPackages which then aren't directly installed onto the system but instead built by the Hydra and only fetched from it as soon as a binary of one of these packages is executed. Doing this only within a NixOS module however isn't enough, because by default gc-keep-outputs is false, so a garbage collect on the Hydra instance would remove the packages we wrap in vuizvui.lazyPackages.
