Many of the fancy `ArrayHandle`s are read-only and therefore connot really create write portals. Likewise, many `ArrayHandle`s (both read- only and read/write) have no way to resize themselves. In this case, implementing the `CreateWritePortal` and `ResizeBuffers` methods in the `Storage` class was troublesome. Mostly they just threw an exception, but they also sometimes had to deal with cases where the behavior was allowed. To simplify code for developers, this introduces a pair of macros: `VTKM_STORAGE_NO_RESIZE` and `VTKM_STORAGE_NO_WRITE_PORTAL`. These can be declared in a `Storage` implementation when the storage has no viable way to resize itself and create a write portal, respectively. Having boilerplate code for these methods also helps work around expected behavior for `ResizeBuffers`. `ResizeBuffers` should silently work when resizing to the same size. Also `ResizeBuffers` should behave well when resizing to 0 as that is what `ReleaseResources` does.
