[scroll-animations] Update view timeline progress calculation to use
localToContainerPoint for subject offset calculation
https://bugs.webkit.org/show_bug.cgi?id=281259
rdar://137715213
Reviewed by Simon Fraser.
Update view timeline progress calculation to use localToContainerPoint for
subject offset calculation, as offsetTop doesn't
calculate the offset from the source, but from the offsetParent. Also add a
simple test to ensure that intermediate transformations
are taken into account.
