LibWeb: Bring BackgroundStyleValue::to_string() to spec

Browse source 
This now outputs valid CSS representing the background, instead of
confusing debug info.

We can't guarantee that all the longhands have the same number of
values, since while that's always the case when parsing, we also create
BackgroundStyleValues when producing the resolved style, which just
combines the longhands together.
