Visualization, Graphic3d - add dedicated structure defining rasterization Pipeline parameters

Currently, rasterization Pipeline parameters (depth test, blending function, stencil test, color/depth writing mask, etc.) are spread around code - depth test in Graphic3d_ZLayerSettings, and blending/stencil are buried inside OpenGl_LayerList.

It could be reasonable defining a dedicated structure defining more comprehensive list of rasterization pipeline parameters at Graphic3d level. This could be useful for more-straightforward graphic-API-agnostic definition of scene graph, e.g. for reusing rendering algorithms (capping, OIT) or at least making their porting from OpenGL simpler (to Vulkan).
