Make instances for them that share code with `nix path-info`, but do a slightly different format without store paths containing store dirs (matching the other latest JSON formats). Progress on #13570. If we depend on the store dir, our JSON serializers/deserializers take extra arguements, and that interfaces with the likes of various frameworks for associating these with types (e.g. nlohmann in C++, Serde in Rust, and Aeson in Haskell). For now, `nix path-info` still uses the previous format, with store dirs. We may yet decide to "rip of the band-aid", and just switch it over, but that is left as a future PR.
