`CSSColorValue`s which have unresolved `calc` components should be able to be resolved. Previously we would always resolve them but with incorrect values. This is useful as we will now be able to now whether we should serialize colors in their normalized form or not. Slight regression in that we now serialize (RGB, HSL and HWB) colors with components that rely on compute-time information as an empty string, but that will be fixed in the next commit.
