  [web-animations] use the keyframe's StyleProperties to determine whether a property is set to "inherit" in a keyframe
https://bugs.webkit.org/show_bug.cgi?id=251432

Reviewed by Antti Koivisto.

Until now we would determine whether a property is set to "inherit" in a keyframe by doing a string
comparison when the Web Animations API is used to set keyframes. However, the StyleRuleKeyframe
created for the keyframe has StyleProperties where the value is parsed, it seems safer to check
the CSSValue rather than do a string comparison here.
