[csswg-drafts] Pull Request: [web-animations-2] Add hold phase

kevers-google has just submitted a new pull request for https://github.com/w3c/csswg-drafts:

[web-animations-2] Add hold phase to an animation (issue #4325)

This PR is an update on https://github.com/w3c/csswg-drafts/pull/5479/, which converts the PR to a delta spec change. The PR introduces addtional factors when calculating the phase of an animation effect.   When using a monotonic timeline,  the boundaries for the before and after phase can be determined based on the start delay, end time and active duration. The phase of a scroll timeline linked animation needs to factor in scroll offsets.  This requirement is achieved by introducing the "current phase" of an animation, which in turn depends on the hold phase when the animation is paused.
