tdf#117295 WIN no main loop shortcut for OLE dialog

Normally we handle Idle events directly without posting events
to the main event queue, as there seem to be no way to post them
to the end of the queue and this starves system events.

This prevents using this short-cut, as the default Windows event
processing doesn't know of this special handling.
Eventually this hack should be removed by simply always processing
all pending events...

This patch includes the follow-up commit 7b148b0edfb2 ("WIN move
native dialog hack into WinScheduler").
