LibWeb/CSS: Expose method for parsing a type of StyleValue

Browse source 
In a few places, user code wants to parse a `<color>` or `<length>` etc,
but we didn't have a way to do so, so they would do something
similar-ish instead, like parse the value of the `color` property.
Let's make that available instead.
