Instead of suppressing only trait errors that are "exact duplicates", display only the "most high-level" error when there are multiple trait errors with the same span that imply each-other. e.g. when there are both `[closure]: Fn` and `[closure]: FnOnce`, omit displaying the `[closure]: FnOnce` bound.
