This replaces the implicit use of the `radius` attribute on the input curves with an input field `Scale` that gets evaluated on the point domain of the input curves to scale the profile. It wasn't super intuitive that the `radius` would actually act as a scale of the profile. E.g. if the radius of the input curve was `1 meter` the resulting profile was unscaled (scaled by 1), but wouldn't necessarily have a size of `1 meter` (only if the profile also had a size of 1m)! If imperial units were used, `3.28084 ft` would correspond to a scale of 1. This change makes this behavior a lot more clear and potentially removes the need for the assumption that the default curve radius is `1.0f` (Ideally, the default curve radius should be `0.01f`). While we did consider making the `Scale` input use the `radius` field implicitly by default, we decided against it, because it again "hides" the dependency on the radius and the fact that the radius is used as a scale. Letting the user make this decision seems better. Pull Request: https://projects.blender.org/blender/blender/pulls/134187
