Now after splitting an object into parts, custom supports, seams, and multimaterial painting are removed, and the user is notified about it.
Also, this commit fixed the text of the notification about removing custom supports, seams, and multimaterial painting by Simplify gizmo. And it also fixed that info about custom supports, seams, and multimaterial painting was still shown in the right panel after the model simplification event when custom supports, seams, and multimaterial were removed.
