Improvement in Convenience through the `EffectsVia EffectDataHandler` wrapper

[ymdfield]

The 'EffectsVia EffectDataHandler' wrapper data type is required for the correct operation of the mechanism that sends effect data to the carrier of the effect system backend based on SendIns/Sig (refer to CEP-02). However, as a result, the type of the carrier for the effect system backend, based on effect data, always requires the application of this wrapper in addition to its original type, resulting in various redundancies.
