DefineMethodOverride defines a method impl. A method impl is a token point to an implementation and a token pointing to a declaration that the body will implement. The body must be defined on the type the method impl is defined and the body must be virtual. The declaration can be made to a method defined on an interface implemented by the type, a method on a derived class or a method defined in the type. If the declaration is on an interface only, the slot defined for the interface is altered. If the declaration is made to a method on a base type then the slot for the method is overridden and any duplicates for the overridden method are also replaced. The method overridden cannot be the actual method declared. If the method is on the same type then the slot is replaced and any duplicates for the replaced methods are overridden.
