efl-mono: Add support for Efl.Class
Efl.Class (in practice, the return from the *_class_get() functions) can be used as argument to functions, like in Efl.Object.provider_find and Efl.Ui.Widget_Factory.item_class(get/set). This commits adds support by representing Efl.Class instances as System.Type in the C# API, allowing someone to do things like: `factory.ItemClass == typeof(MyFramework.MyButton)` It also supports user-defined classes that inherit from efl classes.
