Re: [csswg-drafts] [css-values] Clarify that calc(0) is never a length (#4554)

The spec for `calc()` (once you follow the definitions...) defines that the type of `calc(0)` is <number>, not <length>.

But yes, I agree with @SelenIT's comment that explicitly referencing `<zero>` in the definition of zero-lengths would make things a little clearer.
