Allison Vacanti 813f5a422f Fixup custom portal iterator logic.
The convenience functions `ArrayPortalToIteratorBegin()` and
`ArrayPortalToIteratorEnd()` wouldn't detect specializations of
`ArrayPortalToIterators<PortalType>` since the specializations aren't
visible when the `Begin`/`End` functions are declared.

Since the CUDA iterators rely on a specialization, the convenience
functions would not compile on CUDA.

Now, instead of specializing `ArrayPortalToIterators` to provide custom
iterators for a particular portal, the portal may advertise custom
iterators by defining `IteratorType`, `GetIteratorBegin()`, and
`GetIteratorEnd()`. `ArrayPortalToIterators` will detect such portals
and automatically switch to using the specialized portals.

This eliminates the need for the specializations to be visible to the
convenience functions and allows them to be usable on CUDA.
