Generated serializer with internal access modifier for public class

[EpicDima]

As far as I understand, now the serializer for classes is generated with such an access modifier, that is, public - public, internal - internal. And there is no way to control it. If I'm wrong, please let me know.

I would like to be able to generate the internal serializer and serializer field in the companion object as well.

This can be useful for a library that internally contains public classes that can be used as parameters, but serialization is done entirely internally without additional dependencies and actions on the part of the library user.
Of course, there is an option to use public models and convert them to internal models for serialization, but this is not always possible, for example, because of the large number of objects that will give an overhead because of this.

See #2108 (comment) — we do not have such feature currently, and do not have it in our plans, although it is nice to have it in some cases
