Support generic type adapters

[gfx]

Given an interface EnumDescription and enum EnumA and EnumB which implement EnumDescription, type adapter for EnumDescription can handle its descendants, EnumA and EnumB:

@StaticTypeAdapter(
        targetType = EnumDescription.class,
        serializedType = String.class
)
public class EnumTypeAdapter {

    public static <T extends Enum<T> & EnumDescription> String serialize(@NonNull T value) {
        return value.name();
    }

    @SuppressWarnings("unchecked")
    @NonNull
    public static <T extends Enum<T> & EnumDescription> T deserialize(@NonNull String serialized, @NonNull Class<T> type) {
        return Enum.valueOf(type, serialized);
    }
}
