Remove code duplication from the customCSSText() methods of gradient classes.

Remove code duplication from the customCSSText() methods of gradient classes.

CSSRadialGradientValue::customCSSText and
CSSLinearGradientValue::customCSSText use the same code for building
custom text for color stops. Moving this code into an own method we can
eliminate the code duplication.

Could we maybe call the new function appendCSSTextForDeprecatedColorStops or
something like that (to indicate that it's only for deprecated gradients)?
