LibWeb: Use fixed-point saturated arithmetics for CSSPixels
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
