0023407: Draw face outlines for XDE objects

Browse Source 
FaceOutline aspect and flag added to AIS_Drawer, Prs3d_Drawer.cdl
FaceOutlines computed by StdPrs_ShadedShape and build upon the edge triangulation.
"vshowoutlines" draw command for testing outlines on AIS_Shapes,
"XShowOutlines" draw command for testing outlines on XCAF objects.
remarks corrected:
- FaceOutline renamed to FaceBoundary
- Graphic3d_ArrayOfSegments with edges used instead of Graphic3d_ArrayOfPolylines with bounds.
draw boundaries in separate Graphic3d_Group.
Adding test cases bugs/vis/CR23407_1 CR23407_2
