Bug 1741255 - Add wpt print tests for basic scroll animations. r=hiro

For the following basic cases:
1. a scroll linked animation linked to the root scroller
2. a scroll linked animation linked to an element
3. a scroll linked animation linked to the root scroller of an iframe

There is one assertion in
at-scroll-timeline-default-descriptors-print.tentative.html, and it may not be
related to scroll animations framework, so just mark the max-asserts in meta
file and put the bug number in its comment.
