This commit adds visualization to the selection in curves sculpt mode. Previously it was only possible to see the selection when it was connected to a material. In order to obstruct the users vision as little as possible, the selected areas of the curve are left as is, but a dark overlay is drawn over unselected areas. To make it work, the overlay requests the selection attribute and then ensures that the evaluation is complete for curves. Then it retrieves the evaluated selection GPU texture and passes that to the shader. This reuses the existing generic attribute extraction system because there currently wouldn't be any benefits to dealing with selection separately, and because it avoids duplication of the logic that extracts attributes from curves and evaluates them if necessary.
