[ContentChangeObserver] Difficult to control videos on iqiyi.com as the actions are mouse hover

Reviewed by Simon Fraser.

Source/WebCore:

Decouple isVisuallyHidden and isConsideredVisible. Just because an element is not visually hidden (1px wide content)
it is not necessarily qualified to be visible in the context of hover heuristic (e.g. iqiyi.com brings up a 1px wide
clickable element when hovering over the scrubber. This element is clearly not designed to be actionable.)

[LFC] Fix formatting context root for inflow positioned inline containers
https://bugs.webkit.org/show_bug.cgi?id=199551
<rdar://problem/52728868>

Reviewed by Antti Koivisto.

Relatively positioned (inflow) inline container lives in the formatting context where its parent lives unless
the parent establishes a formatting context. This is slightly different from the usual behavior which is containing block driven.

div id=outer style="position: absolute">><div id=inner><span style="position: relative">content</span></div></div>

While the relatively positioned inline container (span) is placed relative to its containing block "outer", it lives in the inline formatting context established by "inner".

[Pointer Events] Use a gesture recognizer to prevent pinch-to-zoom behavior
https://bugs.webkit.org/show_bug.cgi?id=199543

Reviewed by Dean Jackson.

We used to set the "enabled" property on the main UIScrollView's UIPinchGestureRecognizer to disable pinch-to-zoom
behavior based on the "touch-action" CSS property. This was sub-optimal since this gesture recognizer can be publicly
accessible by third-party developers, but also because it set state instead of a run-time solution.

We now introduce a new WKTouchActionGestureRecognizer dedicated to preventing clearly identified gesture recognizers
from being recognized to disable some built-in behavior. As a new touch starts, we record the computed touch-action
property for the given touch identifier on the WKTouchActionGestureRecognizer, then WKTouchActionGestureRecognizer
determines, by implementing -[canPreventGestureRecognizer:], whether the possibly-prevented gesture recognizer
is known to lead to a pinch-to-zoom behavior and whether it contains a touch that should prevent it.

To support the WKTouchActionGestureRecognizer, WKContentViewInteraction implements the new WKTouchActionGestureRecognizerDelegate
protocol to indicate whether the possibly-prevented gesture recognizer is the main UIScrollView's UIPinchGestureRecognizer.

No new test since this changes the implementation of existing behavior.

Long hang when loading a cnn.com page on iOS

Reviewed by Zalan Bujtas.
Source/WebCore:

Loading https://edition.cnn.com/travel/article/brussels-airlines-flight-to-nowhere/index.html in the iOS 13 sim
results in a long hang under OverlapMapContainer::append(). We were creating pathological clipping scopes with
thousands of entries, because OverlapMapContainer::mergeClippingScopesRecursive() had a logic error where
it added 'sourceScope' to the child instead of 'sourceChildScope'. Add a new assertion to detect that case.

I wasn't able to create a testcase that caused a hang, but a number of existing tests would have
hit the assertion.
