This is the last node to use the `CurveEval` type. Since the curve to points node is basically the same as the resample node, now it just reuses the resample code and moves the curve point `CustomData` to a new point cloud at the end. I had to add support for sampling tangents and normals to the resampling. There is one behavior change: If the radius attribute doesn't exist, the node won't set the radius to 1 for the output point cloud anymore. Instead, the default radius for point clouds will be used. That issue was similar to T99814. Differential Revision: https://developer.blender.org/D16008
