ShapeAppearanceModel. Prior to this change, ShapeAppearanceModel#setAllCorners() and ShapeAppearanceModel#setAllEdges() set all four corners or edges to the same CornerTreatment or EdgeTreatment. This change creates deep copies for each corner/edge treatment to avoid bugs caused by silently reusing the mutable object. PiperOrigin-RevId: 222413898
