feat(nix-compat): Add NixDeserialize and NixRead traits r/8585

Add a trait for deserializing a type from a daemon worker connection.
This adds the NixDeserialize trait which is kind of like the serde
Deserialize trait in that individual types are meant to implement it
and it can potentially be derived in the future.

The NixDeserialize trait takes something that implements NixRead as
input so that you can among other things mock the reader.
