In contrast to the original module all `INLINE` pragmas have been removed.

This is fairly straightforward, although there were a suprising amount of reinternal organization in `base` that was needed for this to happen: * `Data.Foldable`, `Data.Traversable`, `Data.Bifoldable`, and `Data.Bitraversable` share some nonexported datatypes (e.g., `StateL`, `StateR`, `Min`, `Max`, etc.) to implement some instances. To avoid code duplication, I migrated this internal code to a new hidden module, `Data.Functor.Utils` (better naming suggestions welcome). * `Data.Traversable` and `Data.Bitraversable` also make use of an identity newtype, so I modified them to use `Data.Functor.Identity.Identity`. This has a ripple effect on several other modules, since I had to move instances around in order to avoid dependency cycles. Fixes #10448.
