Boris Chiou 3fb6611d01 Bug 1820071 - Make <ray-size> optional and default to 'closest-side'. r=emilio
Per the spec update, the new syntax is:
  `ray() = ray( <angle> && <ray-size>? && contain? )`
And for `<ray-size>`:
  "If no <ray-size> is specified it defaults to closest-side."

So `<ray-size>` is optional and we omit it if it's default value, for
serialization.

By the way, offset=* properties are supported only in Gecko, so we don't
need a servo function to check the preference.
