Fix situation with Data.Enum and Data.Bounded in base

The proposal meant to introduce
Data.Boundedforclass BoundedandData.Enumforclass Enum. Yet inbase-4.20I observeData.Enumwith both type classes, but noData.Boundedat all. There is neither changelog nor@sincepragma. Even more confusingly, this MR is still unmerged. What's happening?
