According to below linked issue(#514), CSSVariableReferenceValue
should have a constructor.
and also fallback attribute should be readonly attribute.
constructor was already added in chromium. but readonly keyword
was not added. so add readonly keyword for fallback attribute.
(actually it is related with #513 to add readonly keyword)
