At the moment, it is not possible to use QMetaObject.invokeMethod with something that requires an argument, as `Q_ARG` and `Q_RETURN_ARG` macros aren't exposed to Python. `QGenericArgument` and `QGenericReturnArgument` should and cannot be used directly.

Use case is invoking a method in a different thread, for example.

Potential workaround until this is fixed: Using a singleshot QTimer with Qt.QueuedConnection.

is duplicated by

PYSIDE-1262 Q_ARG missing, invokeMethod doesn't work currently with arguments in PySide2.
