In this patch, we do these things: 1. Define the mixin and dictionary based on [1]. Note that we have to make the entire mixin nullable to build IDL bindings properly. 2. Implement the parser for the keyframe offset. This includes the UTF8String, TimelineRangeOffset, and CSSNumericValue. For the tests: 1. view-timelines/get-keyframes-with-timeline-offset.html, and view-timelines/timeline-offset-in-keyframe.html depend on Bug 1810248. I have verified it by hacking the rangeStart and rangeEnd APIs on my side. 2. css/timeline-offset-keyframes-hidden-subject.html, and css/timeline-offset-keyframes-with-document-timeline.html are failed becase we don't handle the missing initial/final keyframes properly. Bug 2037642 should take care of this. 3. css/merge-timeline-offset-keyframes.html will be fixed in the following patch.
