Do not build dummy light classes for serialization-related classes

Otherwise, whether LazyLightClassMemberMatchingError happens
or other type of errors because serialization plugin expects
full resolution in the correct module

Currently, only @Serializable annotation leads to exceptions,
but just in case we consider both of them as potentially problematic
