Reviewed by Chris Fleizach.

Added a base template class named AXTreeStore for both AXObjectCache and AXIsolatedTree that implements a map-based storage for instances. The keys in the map are the objects IDs which are assigned on construction. This is necessary to retrieve an instance based on its ID. Retrieving an AXObjectCache or AXIsolatedTree instance is needed for the TextMarker refactoring in https://bugs.webkit.org/show_bug.cgi?id=230558.
