Add "Cursor to Geometry," option for object mode

Pretty simple.

Currently in edit mode if you hit CTRL + S, you can pick "Cursor to selected," and it will put the 3D cursor in the center of the mesh geometry. If you do this in Object mode however, the cursor will only go to the objects origin.

It would be nice to have a separate option in object mode to also snap cursor to objects mesh center. It would help a lot when instancing collections as the origin is usually at the world origin, but i might want to align something to the geometry.
