Reviewed by Tim Horton.

Add support for `<label>` elements in the InteractionRegion generation
code.

* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::interactionRegionForRenderedRegion):
When an element is "labelable", look for label ancestors when doing
element matching.
When a label has a control associated, remove the `cursor: pointer`
requirement, like we do for the control itself.
Group label and control together by using the control's
`elementIndentifier` for both regions.

* LayoutTests/interaction-region/labels-expected.txt: Added.
* LayoutTests/interaction-region/labels.html: Added.
Add a new test file for labels.
