Sam Atkins 443f9e5afb LibWeb/CSS: Make dimension types serialize in resolved form
Some dimensions would always serialize in a canonical unit, others never
did, and others we manually would do so in their StyleValue. This
commit moves all of that into the dimension types, which means for
example that Length can apply its special rounding.

Our local serialization test now produces the same output as other
browsers. :^)
