Redesign Motorized Joint

[michalpelka]

The motorized joint component is POC.
It has multiple features :

• gathering measurements (e.g. protrusion of cylinder)
• compute string PID
• apply torque/force
• print debug info
• apply test signals

Describe the solution you'd like
I would like properly designed components. With small, well-defined features.
Example decoupling:

• Encoder Controller
• PID Controller
• Motor Controller
• Manual Controller (with Dear ImGUI interface)
• Switch to Joint PhysX API

Additional points:

• Remove test logic from this class and add a separate ImGUI base component for testing and tuning motorized joint.
• Remove debug draw entity and use EntityDebugDisplayEventBus instead.

Additional context
Design needs to expose an interface to ROS2: RobotecAI/o3de-ros2-gem#226
