Currently, the expansion example of OBJECT_DECLARE_SIMPLE_TYPE "roughly"
reflects what OBJECT_DECLARE_TYPE is doing.
Why "roughly"? Because this line -
> G_DEFINE_AUTOPTR_CLEANUP_FUNC(MyDeviceClass, object_unref)
- is also wrong for OBJECT_DECLARE_TYPE.
Fix the expansion example of OBJECT_DECLARE_SIMPLE_TYPE, especially
drop that definition of MyDeviceClass.

The 'struct MyDevice' needs to be declared separately.
If the type requires virtual functions to be declared in the class
struct, then the alternative OBJECT_DECLARE_TYPE() macro can be
