Low-level selection algorithms has been improved to explicitly support 2D transformation persistent objects. This patch generally touches: 1) SelectMgr_SelectableObjectSet - the lists of objects has been split onto three subsets (regular, 3d-persistent, 2d-persistent). Each subset has individual BVH tree. The algorithms are now have more flexibility to update only those trees that is really required for actual camera state. 2) SelectMgr_ViewerSelector - explicitly supports Eye space selection operations on BVH tree for 2d-persistent subset. Change of camera position does not anymore affect acceleration data structure (BVH tree) of 2d-persistent selectable objects. 3) Other classes from SelectMgr have been fine-tuned to provide appropriate API. Porting notes: This patch touches very low-level selection classes. If the low-level features were used the following modifications may need to be considered for porting: 1) Iteration over objects of SelectMgr_SelectableObjectSet should now be implemented with corresponding Iterator class. 2) SelectMgr_BaseFrustum::ScaleAndTransform and derived classes return Handle(SelectMgr_BaseFrustum) instead of NCollection_Handle<> type. Small correction of test case for issue CR27739
