Expose fmt::Arguments::from_str as unstable. Now that rust-lang#148789 is merged, we can have a fmt::Arguments::from_str. I don't know if we want to commit to always having an implementation that allows for this, but we can expose it as unstable for now so we can play with it. Tracking issue: rust-lang#148905
