  [cssom-view] Implement Element.prototype.checkVisibility API
https://bugs.webkit.org/show_bug.cgi?id=263223
rdar://117113659

Reviewed by Simon Fraser.

Implement the API defined at: https://drafts.csswg.org/cssom-view/#dom-element-checkvisibility

This is implemented in a way that exclusively queries DOM + style information, to report correct information on skipped subtrees
without performing a forced layout on those subtrees.
