LibWeb: Use fixed-point saturated arithmetics for CSSPixels

Browse source 
Using fixed-point saturated arithmetics for CSSPixels allows to avoid
accumulating floating-point errors.

This implementation is not complete yet: currently saturated
arithmetics implemented only for addition. But it is enough to not
regress any of layout tests we have :)

See https://github.com/SerenityOS/serenity/issues/18566
