It's always `Certainty::Maybe`, so we can trim it down to just the `MaybeInfo` that is within `Certainty::Maybe`. And then the same change can be made to the field of `RerunStalled::WontMakeProgress`, and `goal_remains_stalled` can return a bool, and a hot `matches!` in `try_evaluate_obligations` that never failed can be removed.
