refactor(nix-compat): Move serialization machinery into wire. r/8898

This groups most `wire` feature gated logic into a single module.
The nix_daemon module will be gated by a feature that adds
nix-compat-derive as a dependency.

All of this is a way to break the crate2nix dependency cycle between
nix-compat and nix-compat-derive(which depends on nix-compat for its
doctests).
