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 :)
