Enable visual viewports by default on Mac, and iOS Wk2
https://bugs.webkit.org/show_bug.cgi?id=165452
Reviewed by Zalan Bujtas.
Source/WebCore:
Some tests revealed an issue where, during scrollbar updates, the visual viewport would be
15px wider than the layout viewport, which results in the layout viewport shifting 15px to the
right. Prevent this by disallowing viewport updates during the AdjustViewSize phase; we'll
be called again in postLayoutTasks.
