Improve serialization of scroll-snap-type and scroll-snap-align. When the values
are the same for both dimensions or a default value is used, don't add it to
the list of consumed tokens. The primitive conversion process will handle this
default correctly and serialization will produce a canonical serialization correctly.
We handle this case for both serialization of the style (eg getPropertyValue) and
for serialization of computed style.
No new tests.
* css/CSSComputedStyleDeclaration.cpp:
(WebCore::valueForScrollSnapAlignment): For the computed style don't serialize
the second value if it is the same as the first.
* css/parser/CSSPropertyParser.cpp:
(WebCore::consumeScrollSnapAlign): Only add the second value to the value list if it
exists and if it is different than the first value.
(WebCore::consumeScrollSnapType): Only add the second value if it is a non-default value.
