[Pointer Events] The pointerenter and pointerleave events target the wrong element on iOS
https://bugs.webkit.org/show_bug.cgi?id=197881
<rdar://problem/50187657>

Patch by Antoine Quint <graouts@apple.com> on 2019-05-14
Reviewed by Dean Jackson.

Source/WebCore:

Test: pointerevents/ios/enter-leave-target.html

The "pointerenter" and "pointerleave" should target the element on which the event listener was added and not
the element that would otherwise hit test. This matches the behavior of "mouseenter" and "mouseleave" on macOS.

* page/PointerCaptureController.cpp:
(WebCore::PointerCaptureController::dispatchEventForTouchAtIndex):

LayoutTests:

Add a test where we tap an element that is the child of another element where the parent is the element with the "pointerenter"
and "pointerleave" events registered. The test shows that we correctly set the target to the parent element and not the child.

* pointerevents/ios/enter-leave-target-expected.txt: Added.
* pointerevents/ios/enter-leave-target.html: Added.
