Bug 1493382 [wpt PR 13157] - [PE] Fix fragment clip and paint offset under multicol vertical-rl scrolled, a=testonly

Automatic update from web-platform-tests[PE] Fix fragment clip and paint offset under multicol vertical-rl scrolled

The previous code in VisualOffsetFromPaintOffsetRoot() converting the result
into scrolling contents space used ScrolledContentOffset which mismatched
the new ScrollTranslation which also includes scroll origin. Now use
ScrollTranslation instead.

Also removed the wrong remedy about scroll origin in one of the callers.
