Web Animations: Fix bugs with getComputedTiming() => progress

Project Member Reported by smcgruer@chromium.org, Mar 30 2018

Issue description

We currently fail 6/50 tests relating to the progress from the following WPT test:

  - external/wpt/web-animations/timing-model/animation-effects/simple-iteration-progress.html

The progress is computed in AnimationEffect::UpdateInheritedTime, and is only used for getComputedTiming so hopefully the broken cases will be easy to resolve.

Note that this may just be caused by issue 827577, so that one should be resolved first.

Note this turned out to be more difficult to fix than expected. https://chromium-review.googlesource.com/c/chromium/src/+/989617 is an abandoned partial fix.
