Log Message
Add AXObjectCache::treeData() to retrieve serialized representation of the AX trees.
https://bugs.webkit.org/show_bug.cgi?id=238561
<rdar://problem/91055027>
Reviewed by Chris Fleizach.
Added AXObjectCache::treeData() to retrieve a serialized representation
of both the live and isolated AX trees. The immediate application of
this will be log to file the trees from the browser. Other application
down the road may be to expose a text document-like representation of
the web page for AT clients.
