AX: Add notification for VoiceOver to announce percentage of completion of
isolated tree creation.
https://bugs.webkit.org/show_bug.cgi?id=270395
rdar://122335605
Reviewed by Tyler Wilcock.
VoiceOver responds to the AXLayoutComplete notification by announcing the page
loading progress. This patch combines the percentage of page download with the
isolated tree creation progress to report a single measure of page readiness to
VoiceOver on the AXLayoutComplete notification.
In addition, we are setting the title of the WebArea element to the same
percentage of readiness to allow the VoiceOver user to read it on demand.
Part of this fix involves making AXCoreObject::titleAttributeValue virtual so
that the AXIsolatedObject can override this property when it is set by
reportLoadingProgress.
