Do not access accessibility from qt post routines
It seems accessing accessibility from qt post routines ends
badly since caches are gone already.
Add closingDown() function to web context, which is similar to
QCoreApplication::closingDown(), however return true on
post routine.
Guard delete accessibility calls.
Note the widget part is not necessary, but added for completeness,
since only qml can release profiles due to garbage collection.
