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).
