Add a virtual sendPostedEvents() to QEventDispatcherWin32.

Reimplement this in QWindowGuiEventDispatcher to send both Qt posted events and
queued QPA window system events. We need to do this at a well defined place,
instead of sending events outside of the eventloop from the Windows proc.

This fixes various hangs for example in tst_qinputdialog, which used a 0-timer
to close a dialog.
