0032570: Visualization, AIS_AnimationObject - define rotation around axis

Browse Source 
When using AIS_AnimationObject, linear interpolation is performed from one gp_Trsf transformation to another.
But when an object rotates around a specific axis, the object moves not along a linear trajectory,
but along a circle. Therefore, a separate class AIS_AnimationAxisRotation was created that
allows to animate rotation around a specific axis.

Test case tests/v3d/bugs/bug32570 was added.
