0031652: Visualization - crash on highlighting HLR Computed presentation displayed with Shaded display mode

Browse Source 
PrsMgr_PresentationManager::displayImmediate() now uses proper ZLayer for a shadow presentation
of computed presentation (fixes dynamic highlighting on mouse move).
Graphic3d_CView::SetComputedMode() - added invalidation of bounding box on turning OFF compute mode.
AIS_ViewController::contextLazyMoveTo() now ignores MoveTo() while rotating
view with temporary disabled compute mode (leading to undefined results and crashes).

Graphic3d_Structure::Graphic3d_Structure() - do not copy Graphic3d_TOS_COMPUTED visual
from linked structure, as Graphic3d_CView::SetComputedMode() does not compute such structures.
