Representation-polymorphic HasField (fixes #22156)
This generalises the HasField class to support representation polymorphism,
so that instead of
type HasField :: forall {k} . k -> Type -> Type -> Constraint
we have
type HasField :: forall {k} {r_rep} {a_rep} . k -> TYPE r_rep -> TYPE a_rep -> Constraint
