Export `Monoid(..)`/`Foldable(..)`/`Traversable(..)` from Prelude
This finally exposes also the methods of these 3 classes in the Prelude
in order to allow to define basic class instances w/o needing imports.
This almost completes the primary goal of #9586
NOTE: `fold`, `foldl'`, `foldr'`, and `toList` are not exposed yet,
as they require upstream fixes for at least `containers` and
`bytestring`, and are not required for defining basic instances.
