Add rotation and position parameters to hand-controls.

[filandra]

Description: Added the ability to set the rotation and position of hand-controls. Default rotation and position is aligned with Meta Quest Controllers.

The adjustment for Pico4 has been removed. It set the handModelOrientationX to -45 degrees, which now is the default value. As a result this adjustment is not needed anymore.

This change is addressing issues: #5570, #5305, #5321

Thanks. If any rotation is needed the rotation should be handled internally or hand-controls is not working properly.
