efl-csharp: Fix event struct marshalling.
Summary: The efl.Event struct has a class field that gets generated normally but can be problematic when marshalling the struct back from C to C#. The compilation works fine but when C# runtime tries to marshall the C data (e.g. accessing the Event.Info field), it becomes erratic, either complaining about missing references to object or even segfault. This commit changes the event handling code to use the "Event_StructInternal" struct as is already done when receiving structs from C code. In order to work with other assemblies, the _StructInternal fields were made publit too. Fixes the events tests and the text editor app. Test Plan: make check and run the text editor app in examples repo.
