Until now, we've been using CSS::LengthPercentage, sometimes wrapped in Optional, to represent CSS sizes. This meant we could not support modern values like `min-content`, `max-content`, `fit-content(<length>)`. We were also conflating `none` and `auto` which made the `min-*` and `max-*` properties confusing. The new CSS::Size class covers all possible size values as individual substates. It'll be quite a bit of work to make all layout code aware of the additional features, this patch merely makes the new type available.
