refactor(tvix): move tvix glue code into glue crate r/6936
There's various bits and pieces in tvix-cli that use both the store and evaluator, as well as nix-compat. For example, builtins.derivation, as well as the reference scanning implementation. This "glue code" currently isn't accessible from anywhere else, but it'd be very useful if it were. Move it out into a `glue` crate, and make `tvix-cli` a consumer of it. All the KnownPaths setup and passing around, as well as NIX_PATH handling is also something that should probably be moved into the glue crate as well, but that's something left for a future CL.
