I'm not sure we can remove all these functions from the Concrete classes yet.

For example, an hypothetical scenario:

• A given method returns an interface instance, like, let's say, Efl.IModel Efl.Ui.View.GetModel()
• The C# binding will happily try to use introspection to get the actual Efl_Class* of this instance through Globals.CreateWrapperFor
  • This makes sure we instantiate the actual generated C# class for that given Eo instance if possible.
• But what if this is a non-generated class completely hidden from the binding? Like some kind of "private native model class"?

In this case we would rely on the Concrete class to be able to provide the C# user an instance that implements this interface. It would just wrap the Eo pointer like a regular generated class.

I'm afraid we did not have such test case in our test (thus this patch worked) (or better comments explaining the reasoning for keeping these classes around).

PS: Except for the rebase, looks good and tests passes.
