We have some basic implementation already, and it'd be better to enable
this perference earlier for interop estimation purpose, so we can show the
correct result on web-platform-tests dashboard.

Per https://treeherder.mozilla.org/jobs?repo=try&revision=334cc4eb44cca39eafa8809025210b2868b94771&selectedTaskRun=FkqsN6kAQ8izNdOqjqiClg.0&searchStr=Linux%2C18.04%2Cx64%2CWebRender%2Cdebug%2CWeb%2Cplatform%2Ctests%2Ctest-linux1804-64-qr%2Fdebug-web-platform-tests%2Cwpt8

There are some failures in css/css-animations/parsing/animation-computed.html. So we probably have to upload a patch which enable the preference in this folder first and fix the failures.

Also, we have to tweak the serialization of animation shorthand.
We serialize animation shorthand only when animation-timeline is the
initial value (i.e. time-driven animations), so the resolved value of
animation-duration component is always 0s.

:boris could you consider nominating this for a release note? (Process info)
We could include it in the nightly only release notes.

Release Note Request (optional, but appreciated)
[Why is this notable]: We enable scroll-driven animations for experimental purpose. There are some basic implementation in Gecko, and after enabling this feature on Nightly we can show the proper status on WPT dashboard, for interop purpose. That means all browser vendors can understand Gecko implementation status via Web-platform tests, and it'd be easier for us to make the decision to champion scroll-driven animations into the focus areas in the following years.
[Affects Firefox for Android]: Yes
[Suggested wording]: Enable scroll-driven animations experimentally in Nightly.

We can see our current implementation status on WPT dashboard now, e.g. https://wpt.fyi/results/scroll-animations?label=master&label=experimental&product=chrome&product=firefox&aligned.

The score is about 47% today.
