Support binding WeakPtr<> to methods with void return types.
This should give functionality similar to ScopedRunnableMethodFactory.
Note that binding a WeakPtr only make sense with methods with void return types. If the return type is not void, then it is unclear what the function should return when the pointer is invalidated.
This code adds a compile time assert to check the return type.
