Assets: Disable snap-dragging for linking object assets

The location of a linked object isn't editable, or at least it will be reset
when reloading the file. So the drag & drop shouldn't even pretend like this
would work, so disable the snapping of the object and the bounding-box to show
the snapped object location while dragging.
