Reviewed by Tyler Wilcock.

The [WebAccessibilityObjectWrapper accessibilityPresenterProcessIdentifier] method was calling WebCore::presentingApplicationPID() that cannot be called off the main thread. This patch fixes this by caching the ProcessID in the AXIsolatedTree, so that it can be retrieved off the main thread.
