Refactor MovingPlatformComponent to support subcomponents for movement and rotation

- Introduced PlatformSubComponent as a base class for platform movement logic.
- Added MoverSubComponent for standard path-following behavior.
- Implemented SimpleMoverSubComponent for auto-generating two-waypoint paths.
- Created RotatorSubComponent to handle angular velocity and rotation along paths.
- Updated MovingPlatformComponent to manage multiple subcomponents and their states.
- Modified serialization and update logic to accommodate new subcomponent architecture.
- Adjusted GameMessages to include additional parameters for platform state synchronization.
- Enhanced SimplePhysicsComponent to prevent double movement when on a moving platform.
- Added new CMakeLists.txt for organizing MovingPlatformComponent files.
