The new-style `ArrayHandle` uses `Buffer` objects to manage data. Thus,
when one is decorating the other, it expects to find the `Buffer`
objects, which the old-style `ArrayHandle`s do not have. To make the two
work together, fake buffers in the old-style arrays.
The buffers in old-style arrays are empty, but have metadata that points
back to the `ArrayHandle.
Previously, when you got a host/control portal from
`ArrayHandleVirtual`, you got a version of an `ArrayPortal` that manged
its own reference to the virtual structure that was implementing the
portal. This was not done for device/execution portals because those
objects could not do the appropriate resource management from the
execution environment.
Rather than releasing the host object to the portal, keep the host
object managed by `StorageVirtual`. This allows the control and
execution portals to be the same type, which we will need to be friendly
with new array objects.
1. The code now works without CUDA_LAUNCH_BLOCKING set by using explicit
synchronizations where required.
2. The code has also been modified to use thread specific memory spaces,
which for Kokkos' Cuda backend means per thread streams.

As we update the `ArrayHandle`s to the new buffer style, simplify
`ArrayHandleSwizzle` by implementing it on top of
`ArrayHandleTransform`. Also, introduce some C++11 template concepts to
handle variable arguments better.
In this conversion, some features have been removed. Previously if the
swizzle dropped some components, you were still allowed to write to the
array. This would be an in place write that would only update the passed
components. This feature has been removed and if any components are
dropped, the array becomes read only. If all components are swizzled,
then the array becomes writable (through templating).
Another lost feature is that the swizzle map is no longer checked for
correctness. The array handle just assumes that the indices are correct.
It should be noted that it does not look like `ArrayHandleSwizzle` is
actually used anywhere. If it is not used by any customers, we may
want to consider deprecating the class.
The old version of `ArrayHandleCompositeVector` would check (at
construction) to make sure that all the arrays had the same length. This
check has been removed because (1) it did not always catch all problems
(such as if the input arrays change), (2) debug builds check for out-of-
range array accesses anyway, and (3) it required a lot of extra template
expansion.
Because that check has been removed, also remove the part of the
`ArrayHandleCompositeVector` test that checks this check.
When `ArrayHandleCompositeVector` has only 1 component, it is supposed
to have a special template that uses the base value type rather than a
`Vec` of that type. However, the `Storage` with the value type was
missing. I'm not sure how we weren't getting compile errors before, but
moving to the new buffer arrays seems to bring about the expected error.
The `StorageImplicit.h` header is no longer used. However, just removing
it causes compiles to fail if they include it. To make the transition
better, re-add this file, but cause a deprecation warning if it is
included.
