LibWeb: Sort and group CSS Length units as they are in the spec

They previously weren't sorted at all. Alphabetical would be nice, but
then things like `em` and `rem` would be separated. So, let's copy the
spec's order. That way it's easier to keep track of which units we have
or haven't implemented. (Since there are so many...)
