refactor(tvix/eval): rm From<(T, Option<Box<NixContext>>)> for NixString HEAD r/8911 canon

This conversion was a bit too magic, and we can just use
`NixString::new_context_from` without having to worry about the
distinction between an empty context or no context, as
NixString::new_context_from already deals with that internally.
