IntersectionObserverEntry.boundingClientRect ignores

Reviewed by Simon Fraser.
Element::getBoundingClientRect() routes through Document::zoomForClient(),
which honors the GetBoundingClientRectZoomedEnabled setting and skips the
absolute-to-client zoom division when enabled.
IntersectionObserver::updateObservations bypassed that helper and passed
style().usedZoom() directly to absoluteToClientRect, so its reported
rects were always divided by usedZoom and disagreed with
getBoundingClientRect() under the default pref. Route through
Document::zoomForClient() so the entry rects match.
