imported/w3c/web-platform-tests/css/css-view-transitions/no-white-flash-before-activation.html can time out in some cases
(seen on iOS and Intel bots on https://github.com/WebKit/WebKit/pull/22531).

This probably happens with that PR because nothing else triggers a rendering update after clearing rendering
suppression. So fix `Document::clearRenderingIsSuppressedForViewTransition()` to schedule a rendering update.

Also add more to the ViewTransition log channel.
