Log Message:
-----------
AX: Move AXPosition off the main thread for ScrollView and WebArea objects
during the isolated tree construction.
https://bugs.webkit.org/show_bug.cgi?id=256644
<rdar://problem/109205791>
Reviewed by Chris Fleizach and Tyler Wilcock.
- Added the AXIsolatedTree::createEmptyContent method to allow for the
customization of the Scrollview and WebArea properties for the empty, temporary
isolated tree.
- Cache the ScreenRelativePosition for these objects in the empty isolated tree
so that it is not needed to hit the main thread upon client's request of this
property.
- Some code re-factoring was needed, namely, the addition of
AXIsolatedTree::resolveAppends() and queueAppendsAndRemovals.
