Reviewed by Ryosuke Niwa.

In order to improve performance when requesting the accessibility hierarchy, we introduce the idea of a "static accessibility tree" which
could be accessed on a different thread by assistive technologies.
That is accomplished by storing all the data needed to answer accessibility attribute queries in a static object that mirrors the
"live" AccessibilityObjects (which interact with both DOM and Render trees).
These static objects are generally created after layout is done and final tasks are being performed. They are then stored in the static tree
representation and able to be read from anywhere.
Tactically this is done with AXIsolatedTreeNodes inside of an AXIsolatedTree. The TreeNodes implement an AccessibilityObjectInterface shared
with AccessibilityObject.
This allows the wrappers to access either one depending on conditions and platforms without significant code duplication or re-organization.
