Visualization tools for the ApplyForceTorque GUI plugin (#2051)

Adds visualization tools to the new ApplyForceTorque GUI plugin. This allows the user to see the force (represented by an arrow) and the torque (represented by a circle) displayed on the scene at their application point before applying them. --------- Signed-off-by: Henrique-BO <[email protected]>
