[web-animations-2] Make active boundary times inclusive if timeline duration is finite

Addresses issue #5223. The discussion suggested adding rules for resolving fill "auto".  This approach introduces edge cases as indicated in comments on https://github.com/w3c/csswg-drafts/pull/6673.  In short, resolving fill 'auto' introduces potential surprising behavior when delays or timeline offsets are non-zero.  The before and after phase calculations had explicit rules to make an active boundary exclusive depending on the direction of the animation.  This PR restricts these exclusion rules to non-finite timelines.
