Log Message:
-----------
The InteractionRegion layers' order should match the paint order

<rdar://105700167>
Reviewed by Tim Horton.
Propagate the Interaction Regions creation's order (which matches the
paint order) all the way to the RemoteLayerTree.
The content process is now in charge of ordering/deduping the regions.
And we don't do per-element region uniting anymore.
* Source/WebCore/rendering/EventRegion.h:
Remove the InteractionRegionByElement HashMap.
Add HashSets to dedupe regions by bounds.
* Source/WebCore/rendering/EventRegion.cpp:
(WebCore::EventRegionContext::uniteInteractionRegions):
(WebCore::EventRegionContext::copyInteractionRegionsToEventRegion):
Use a vector to accumulate interaction regions in order.
Prevent duplicated bounds.
(WebCore::EventRegion::dump const):
Remove the test-only ordering code so existing tests cover the actual order.
*
Source/WebKit/UIProcess/RemoteLayerTree/RemoteLayerTreeInteractionRegionLayers.mm:
(WebKit::insertInteractionRegionLayersForLayer):
Break when the first non-InteractionRegion-layer is encountered.
(They always come first.)
(WebKit::updateLayersForInteractionRegions):
Update the sublayers while maintaining the order we get from the event
region. Reuse existing layers when the bounds match.
* LayoutTests/interaction-region/overlap-expected.txt: Added.
* LayoutTests/interaction-region/overlap.html: Added.
Add a test covering the content-side deduplication.
* LayoutTests/interaction-region/split-inline-link-expected.txt:
* LayoutTests/interaction-region/wrapped-inline-link-expected.txt:
Update test after the per-element uniting removal.
