Add method to get NSPrintInfo* from QPrintEngine in Cocoa plugin

Add an invokable method that takes the QPrintEngine (which will
always be a QMacPrintEngine) and return the NSPrintInfo* from the
QMacPrintEnginePrivate. This will be used by the native dialogs in
QtPrintSupport to get/set printer settings.
