Deletion of SketchSolve blocks using the Rust API

[pierremtb]

@jtran Yeah I agree with the sentiment #9712 (comment)

The reason I wired it up the old way was to quickly get a sense of feature tree interactions with constraints and sketch blocks, and see how we should prioritize in-scene rendering and selectability of constraints, without having to get a new deletion code path going.

But yeah that was probably short-sighted and it shouldn't be too hard now that I think about it and I'll be happy to do it in a follow-up. Thanks for the link! How hard would it be to get a similar API for constraint deletion?

Constraint deletion works via deleteObjects(). Editing constraints is the one that's not implemented yet.

@jtran Awesome, thank you! I didn't realize this one could work for constraints. Consider that deleteFromSelection block removed 🫡
