AX: [WKAccessibilityWebPageObject accessibilityAttributeValue:] should
retrieve several properties from the main thread.

Reviewed by Tyler Wilcock.
Several of the AX API attributes including NSAccessibilityWindowAttribute and
NSAccessibilityPrimaryScreenHeightAttribute need to be retrieved from the main
thread. Among other problems, this may be the cause of intermittent crashes we
observe in accessibility/primary-screen-height.html. This patch changes this
method to execute on the AX thread only those properties that are safe off the
main thread, and to dispatch to the main thread the rest.
