Order the VTK scalar types to favor used types

Reorder the `VTKScalarTypes` to put the repeated types at the bottom.
This will avoid using types like `long` that are essentially the same as
other types (e.g. `long long`) but will still be considered different.
This causes problems when checking against some VTK types (such as
`vtkIdType`).
