Migrate Bifoldable and Bitraversable instances for Constant

These were originally defined in the bifunctors library. The Data.Bifoldable
and Data.Bitraversable modules will be moved to base in base-4.10, so this
commit moves the corresponding instances for Constant to transformers to
accommodate the migration.
