afohrman a10070b6b3 Unify the creation of default CornerTreatments and EdgeTreatments.
Change the default CornerTreatment created in MaterialShapeUtils from CornerTreatment() to RoundedCornerTreatment(0). This matches the default previously created from ShapeAppearanceModel constructors.

This change unifies the defaults created in ShapeAppearanceModel's constructors with the default created by MaterialShapeUtils, by converging the two default corner and edge treatment creation methods into one method in MaterialShapeUtils. That method is then called from MaterialShapeUtils#createCornerTreatment#createCornerTreatment() and ShapeAppearanceModel's constructors.

This change also renames getDefaultCornerTreatment() to createDefaultCornerTreatment() to convey that the method instantiates an object.
