bec07d4af7 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

7115446995 LibWeb: Support font-size: calc()
Now that we have a way to resolve calc() lengths without a layout node,
we can finally support calc() values in font-size.

This wasn't possible before because font-related properties have to be
resolved eagerly in StyleComputer due to font-relative CSS length units
depending on the computed font being known.
