feat(tvix/vm): implement construction of optimised KV attrsets r/4438
For name/value pairs (which occur extremely often in Nix and make up a significant chunk of the runtime cost of evaluating nixpkgs) we substitute an optimised representation. For now this will only be used if the name/value pair keys were specified as literal identifiers or strings (i.e. if chunks are encountered as keys they are not forced and a normal attribute set backed by a map will be constructed).
