Integrate resize event with HTML5 event loop
https://bugs.webkit.org/show_bug.cgi?id=202964

Reviewed by Geoffrey Garen.

Source/WebCore:

Dispatch resize events in "run the resize steps" during the "update the rendering":
https://html.spec.whatwg.org/multipage/webappapis.html#update-the-rendering

Exisitng code in WebCore which was dispatching or scheduling dispatching of resize events now simply sets
a flag on document and schedules a rendering update. In Page::updateRendering, we fire resize events on
any documents with this flag set.

Test: fast/events/resize-subframe-in-rendering-update.html

* dom/Document.cpp:
(WebCore::Document::setNeedsDOMWindowResizeEvent): Added.
(WebCore::Document::setNeedsVisualViewportResize): Added.
(WebCore::Document::runResizeSteps): Added. https://drafts.csswg.org/cssom-view/#run-the-resize-steps
* dom/Document.h:
* page/DOMWindow.cpp:
(WebCore::DOMWindow::resizeTo const):
* page/FrameView.cpp:
(WebCore::FrameView::sendResizeEventIfNeeded): Now sets m_needsDOMWindowResizeEvent on Document instead of
enqueuing a resize event.
* page/Page.cpp:
(WebCore::Page::updateRendering): Call runResizeSteps on each document.
(WebCore::Page::collectDocuments): Added.
* page/Page.h:
* page/VisualViewport.cpp:
(WebCore::VisualViewport::enqueueResizeEvent):

LayoutTests:

Added a regression test and fixed an existing test to work with the new behavior.
