0024623: Visualization - improve selection mechanism

Browse Source 
Redesign of selection mechanism:
- implemented 3-level BVH tree for selection;
- selection now calculates in 3D space;
- intersection tests were moved to SelectMgr_BaseFrustum descendants;
- removed .cdl files in Select3D and .cdl related to selection in MeshVS;
- SelectMgr_ViewerSelectors are now shared between local and global contexts;
- transformations of sensitive entities are now stored in SelectMgr_SelectableObject only. Sensitive entities are independent from transformations, it is applied to SelectMgr_SelectingVolumeManager instance only;
- connected and multiple connected interactive objects are now represented by their child objects only for SelectMgr_SelectionManager;
- if interactive object has child objects, they will be stored as separate objects in SelectMgr_SelectionManager now.
- test cases bugs/vis/bug24623_1, bug24623_2, bug24623_3, bug24623_4 to test performance and memory issues.
