feat(tvix/eval): implement attrset update (`//`) operator r/4475
The underlying implementation does a few tricks based on which pair of attrset representations is encountered. Particularly the effect of short-circuiting the empty cases might be relevant in nixpkgs/NixOS, due to the use of lib.optionalAttrs.
