Introduce QWindowSystemInterface::handleSynchronousCloseEvent
And use it from the Cocoa backend.
In general, for threaded GL rendering to work, any function that
affect the surface must be synchronous, so the implementor (such as
QQuickCanvas) can pick it up and block until the GL context has
released the surface. Otherwise, we will crash.
