Reviewed by Tim Horton.

HTMLAnchorElements with no `href` don't have the `isLink` flag set. But
we're sitll seeing instances of `<a onclick="...">`.
Since we already have the `EventListenerRegionType::MouseClick` check,
add HTMLAnchorElement to the list of elements that get
InteractionRegions even without `cursor: pointer`.

* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::shouldAllowNonPointerCursorForElement):
Add HTMLAnchorElement to the list.

* LayoutTests/interaction-region/inline-link-expected.txt:
* LayoutTests/interaction-region/inline-link.html:
Update the test to cover the "onclick-only" scenario and the scenario
where a link has neither a href nor a click event listener (and doesn't
get a region).
