A couple of arbitrary substitution functions require us to get or produce some style value, and then substitute its ComponentValues into the original ComponentValue list. So this commit gives CSSStyleValue a tokenize() method that does so. Apart from a couple of unusual cases like the guaranteed-invalid value, style values can all be converted into ComponentValues by serializing them as a string, and then parsing that as a list of component values. That feels unnecessarily inefficient in most cases though, so I've implemented faster overrides for a lot of the basic style value classes, but left that serialize-and-reparse method as the fallback.
