0027818: Visualization - provide an interface to define highlight presentation properties

- introduces a wrapper for setting up highlight properties: Graphic3d_HighlightStyle;
- API of all methods that use highlight or selection color is changed to deal with Graphic3d_HighlightStyle;
- highlight in shading mode now supports transparency, implemented via blending;
- transparency for selection can also be set, but implementing custom entity owners with additional presentation on application level;
- methods PrsMgr_PresentationManager::Highlight, PrsMgr_PresentationManager::BoundBox that highlight object with hard-coded color are removed;
- deprecated methods of SelectMgr_EntityOwner, that use presentation manager's highlight method, were removed;
- methods of IsHilighted AIS context with selection color checks were replaced;
- added API to store dynamic and selection highlight to Prs3d_Drawer class;
- customization of dynamic and selection highlight for particular objects is now available through SelectMgr_SelectableObject::HilightAttributes();
- AIS_InteractiveContext highlight methods were updated to support individual highlight styles of interactive objects;
- introduced new command - vselprops, that allows to customize global selection and highlight properties like autoactivation, pixel tolerance and colors;
- Draw Harness commands vautoactivatesel and vselprecision were removed, use vselprops instead;
- fixed bug in command's parser;
- test case for issue #27818
