[PhysX] Articulation joint Motion - "Limited" can be broken by force
How to reproduce:
1. Open the user's attached project ("ArmRobot.zip")
2. Enter Play mode
3. Aim at the robot arm and shoot spheres clicking "Space Bar" until the "Base" is forced to rotate and spin out of control
Expected results: The "Base" of the robot arm does not rotate because Motion is set to "Limited"
Actual results: The "Base" of the robot arm is forced to rotate and spins out of control
Reproducible with: 2020.1.15f1, 2020.2.0b13, 2021.1.0a7
Couldn't test with: 2018.4.29f1, 2019.4.15f1 (PhysX didn't have Articulation Bodies yet)
