+ Replace PlatformCAAnimationRemote::KeyframeValue with Variant
+ https://bugs.webkit.org/show_bug.cgi?id=225474
+
+ Patch by Ian Gilbert <iang@apple.com> on 2021-05-15
+ Reviewed by Ryosuke Niwa.
+
+ KeyframeValue was effectively a Variant. Replaced the existing class with a WTF::Variant.
+
+ No test as this does not change code behavior.
