0026641: Visualization, TKOpenGl - handle correctly transformation persistence within perspective projection.

Browse Source 
Add a new method AIS_InteractiveContext::SetTransformPersistence, which sets transform persistence to object and selection.
Add a new method SelectMgr_SelectionManager::UpdateSelection, which re-adds selectable object in BVHs in all viewer selectors.
Add a new method SelectMgr_ViewerSelector::MoveSelectableObject, which moves object from set of not transform persistence objects to set of transform persistence objects (or vice versa).
Add a new method Graphic3d_TransformUtils::Convert, which converts gp_Trsf to Graphic3d_Mat4.
Remove the method PrsMgr_PresentableObject::SetTransformPersistence(flag, point).
