[cr140] Migrate SkusJSHandler to gin::Wrappable

This class had been moved to `gin::DeprecatedWrappable` with all the
other classes, but now it is being migrated to the modern version we are
supposed to use.

    [gin] Delete DeprecatedWrappable

    This CL deletes gin::DeprecatedWrappable, and classes and data
    structures related to gin::DeprecatedWrappable. Additionally it removes
    internal fields of JS wrapper objects that were only used by
    gin::DeprecatedWrappable, but are not needed anymore with the new
    gin::Wrappable.
