LibWeb: Add BackgroundSizeStyleValue

Browse source 
There's nothing really background-size-specific about this, but since
there is no `<size>` value type defined in the CSS spec at this time,
and background-size is the only user of it, I think this name makes more
sense. But I'm not 100% convinced.
