This commit adds a node to output the convex hull of any input geometry as a mesh, which is an enclosing geometry around a set of points. All geometry types are supported, besides volumes. The code supports operating on instances to avoid copying all input geometry before the operation. The implementation uses the same backend as the operation in edit mode, but uses Mesh directly instead of BMesh. Attribute transfer is not supported currently, but would be a point of improvement for the future if it can work in a predictable way on different geometry input types.
