AX: Avoid hitting the main thread on "AXTextMarkerIsValid" calls.
https://bugs.webkit.org/show_bug.cgi?id=251688
<rdar://problem/105005458>
Reviewed by Chris Fleizach.
Added AXTextMarker::isValid which returns true if an AX object can be obtained
from the TextMarker.
Since the objects can be either isolated or not, several changes were required
to AXTreeStore, including separating the collections of live and isolated
trees. Now an isolated tree has the same ID as the AXObjectCache that created
it.
In addition, added the distinction between an TextMarker being null or valid,
and adjusted related tests and WTR AX JS interface accordingly.
Some code cleanup and renaming.
