Log Message:
-----------
Don't use CSSParserFastPaths to parse declarations inside at-rules
rdar://152190645
https://bugs.webkit.org/show_bug.cgi?id=293710
Reviewed by Tim Nguyen and Antti Koivisto.
At-rules like @keyframes or @position-try restrict what CSS properties
can be declared in the rule. This logic is present in the "slow"-path
parser (CSSPropertyParser) but not in the fast path parser. Since it's
rare to parse at-rules with declarations inside anyway, this patch
forces declarations inside at-rules to use the slow path instead
of the fast path.
