feature request: `NonLinearShapeCastOptions`

[lotus128]

Currently, there is a ShapeCastOption for shapecasts. However, no such API exists for non-linear shapecasts.

I would like a NonLinearShapeCastOption for non-linear shapecast, so that we can have feature parity with shapecasting.

My specific use case requires target_distance which I was able to work-around by creating a new collider.
