[@scroll-timeline] Effectively pause animations in flaky WPT

The last test in at-scroll-timeline-dynamic.tentative.html expects
zero time to have passed between the first and second calls to
'await assert_width(...)', when in reality several frames worth of
time has passed. This causes flakiness on bots.

We don't actually care about exactly where we're at on the document
timeline in this test file, only whether or not we are currently on
that timeline. Hence this CL uses the steps() function to effectively
"stop" document-timeline-attached animations for a full minute.
