Reviewed by Tim Horton.

Use masked corners to "shrink wrap" grouped InteractionRegions. And
make them fit the element's visual style better.

* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::interactionRegionForRenderedRegion):
Lookup the `borderRadius` on the region's renderer and not the renderer of
the matched element.
Only apply inline bounds inflation and minimum border radius to
renderers without a visual edge.

* Source/WebCore/rendering/EventRegion.cpp:
* Source/WebCore/rendering/EventRegion.h:
(WebCore::EventRegionContext::shrinkWrapInteractionRegions):
(WebCore::EventRegionContext::copyInteractionRegionsToEventRegion):
Introduce a new method to edit the masked corners on grouped
InteractionRegions and make them more visually pleasing.
