LibWeb: Fix CSS opacity parsing

Browse source 
The StyleProperties code for opacity existed before NumericStyleValue
was a thing, and was affected by over-enthusiastic unitless-length
parsing, so it assumed everything was a length. Now it matches the
Color4 spec instead, accepting either a number, or a percentage.

We also get to remove the hack! :^)
