-----------
Update handling of opacity values to match latest spec resolution
https://bugs.webkit.org/show_bug.cgi?id=296725
Reviewed by Darin Adler.
Updates the parsing and resolution of opacity values to match latest spec
resolution in w3c/csswg-drafts#10426
Opacity values now parse using the `consumePercentageDividedBy100OrNumber`
rules, meaning that percentage tokens get converted to numbers at parse
time, but calc() functions are not converted until style building. This
means updating both the CSSProperties.json grammars and the fast path.
