Make it so that aspect ratio behaves like auto if it is 0 or inf

Summary: We do not validate the aspect ratio to ensure it is non zero and non inf in a lot of places. Per the spec, these values should act like auto. There is no auto keyword, but it is the default so I just set the style to a default FloatOptional in this case
