libcamera: bound_method: Propagate method return value
Propagate the return value of the bound method all the way to the caller of activate(). The value is stored in the arguments pack for indirect invocation. As C++ doesn't allow instantiating a variable of type void, we need to specialize the template class BoundMethodPack for methods returning void. This in turn requires template specialization for the BoundMethodArgs class in order to store the return value in the pack, and for the BoundMemberMethod class to extract the return value from the pack.
