Remove includes of callback_forward.h from .cc files

Generally, .cc files should not be forward declaring base::OnceCallback
and related classes. If they are using Callbacks, they should include
callback.h instead. So treat the base/functional/callback_forward.h
includes as superfluous and remove them.
