Consistently use edge draw flag instead of original index to determine if an edge should be drawn or not. In GPU subdivision the edge original index was used for both edge optimal display and selection mapping to coarse edges, but they are not the same. Now match the CPU subdivision logic and use a separate edge draw flag VBO. For cage display, match Blender 3.3 behavior more in showing/hiding of edges in wireframe mode. That is edges without a mapping to an original edge are always hidden when there is no distinct cage, and drawn otherwise. This is not ideal for e.g. the bevel modifier where it will always show some edges on corners despite all edges being hidden by the user. But we currently have no good information to decide if these should be hidden or not, so err on the side of showing too much as it did before.
