Add `parseFlakeRef` and `flakeRefToString` builtins (#8670) Over the last year or so I've run into several use cases where I need to parse and/or serialize URLs for use by `builtins.fetchTree` or `builtins.getFlake`, largely in order to produce _lockfile-like_ files for lang2nix frameworks or tools which use `nix` internally to drive builds. I've gone through the painstaking process of emulating `nix::FlakeRef::fromAttrs` and `nix::parseFlakeRef` several times with mixed success; but these are difficult to create and even harder to maintain if I hope to stay aligned with changes to the real parser/serializer. I understand why adding new `builtins` isn't something we want to do flagrantly. I'm recommending this addition simply because I keep encountering use cases where I need to parse/serialize these URIs in `nix` expressions, and I want a reliable solution.
