chore(tvix/eval): provide 'static references to "name"/"value" r/4701
These static strings show up a bunch when dealing with the internals of attribute sets, and having them available as static references is required. Due to the way const expressions are evaluated, taking a reference to the existing NixString::NAME / NixString::VALUE items does not work and the references themselves need to be const-evaluated.
