 Make Generic1 poly-kinded

 This generalizes the `Generic1` typeclass to be of kind `k -> *`, and
 this also makes the relevant datatypes and typeclasses in `GHC.Generics`
 poly-kinded. If `PolyKinds` is enabled, `DeriveGeneric` derives
 `Generic1` instances such that they use the most general kind possible.
 Otherwise, deriving `Generic1` defaults to make an instance where the
 argument is of kind `* -> *` (the current behavior).

 Fixes #10604. Depends on D2117.
