Bug 1547231 introduced aspect-ratio property, and the current spec uses auto | <ratio> syntax on apect-ratio. The wpt is also updated by Chrome. So it's time to update its syntax.

Status: NEW → ASSIGNED

In order to test its parsing and serialization, we expose it but protect
it behind a pref.

Also, we drop the pref, layout.css.aspect-ratio-number.enabled, becacuse
the spec of css-sizing-4 uses Number now.
