  Remove some downcasting in Element
https://bugs.webkit.org/show_bug.cgi?id=267585

Reviewed by Chris Dumez.

Instead of shouldObtainBoundsFromSVGModel() that returns a boolean,
have elementWithSVGLayoutBox() that returns a RefPtr. Deduplicates
downcasting and clarifies the code.

* Source/WebCore/dom/Element.cpp:
(WebCore::elementWithSVGLayoutBox):
(WebCore::Element::boundsInRootViewSpace):
(WebCore::Element::absoluteEventBounds):
(WebCore::Element::getClientRects):
(WebCore::Element::boundingAbsoluteRectWithoutLayout const):
(WebCore::shouldObtainBoundsFromSVGModel): Deleted.
