0023044: Regression: 3D views are not invalidated by some modifications of OpenGl_Structure

myIsUpdated flag and Invalidate() method removed from OpenGl_Workspace class.
View redrawing is made unconditional.
V3d_View::Update() becomes deprecated and should be replaced with V3d_View::Redraw().
V3d_Viewer::Update() becomes deprecated and equivalent to Redraw()
