Previously the type is the auto-generated struct/union type. This CL changes it to the corresponding DataView type.
The reason of doing this? The DataView type is shared by the chromium and blink variants of generated bindings, while the generated struct/union type is not. By changing StructTraits/UnionTraits to be specialized by the DataView type, users will be able to use the same StructTraits specialization in both variants.
