The trim functionality is implemented in the geometry module, and generalized a bit to be potentially useful for bisecting in the future. The implementation is based on a helper type called `IndexRangeCyclic` which allows iteration over all control points between two points on a curve. Catmull Rom curves are now supported-- trimmed without resampling first. However, maintaining the exact shape is not possible. NURBS splines are still converted to polylines using the evaluated curve concept. Performance is equivalent or faster then a 3.1 build with regards to node timings. Compared to 3.3 and 3.2, it's easy to observe test cases where the node is at least 3 or 4 times faster. Differential Revision: https://developer.blender.org/D14481
