feat(tvix/serde): initial Nix->serde::Deserialize impl r/5566

This will make it possible fairly easily use Nix to represent
arbitrary data structures, e.g. for using Nix as a config language.

Only pure Nix (i.e. no `import` etc.) is supported for now.

Not all types, specifically no struct traversal, are implemented in
this commit.
