Skip vtkDataObjectImplicitBackendInstantiateIdType
Since vtkIdType is just a typedef for one of the fundamental integer types for which the template is already instantiated, we must avoid instantiating for vtkIdType since the instantiation will result in duplicate template symbols. Most linkers will handle the duplicated template symbols, but some linkers will generate an error.
