Add IOSim POR support for QSM

Parallel QSM tests can be more effective in detecting potential race conditions if QSM supports IOSIm POR. We should add support for it to the library to increase the robustness of our code.

Start by locating the QSM library and its parallel test setup, then identify how IOSim POR is exposed and used. Compare the existing QSM execution path with the IOSim POR support, and consider the work done when parallel QSM tests can use IOSim POR to improve race-condition detection.
