Refactoring RendererD3D to not have virtual functions for state calls

BUG=angleproject:1242 Draw calls get called many times. Eliminating the number of virtual function calls will help with performance. Renderer9 and Renderer11 now have diverging paths for managing state with the dirty bits. Hence, we can remove some of the virtual calls.
