chore: remove legacy termination_by' (#5426) This adds a couple of WellFoundedRelation instances, like for example WellFoundedRelation (WithBot Nat). Longer-term, we should probably add a WellFoundedOrder class for types with a well-founded less-than relation and a [WellFoundOrder α] : WellFoundedRelation α instance (or maybe just [LT α] [IsWellFounded fun a b : α => a < b] : WellFoundedRelation α).
