Add test to initiate print preview with expected document composition to be PDF or XPS, depending upon kUseXpsForPrinting feature flag. This includes some plumbing and data format query support routines that allow Print Preview observers to determine which format the generated document is. This test demonstrates that the Print Compositor is still generating PDF for the document even when the feature flag is enabled for generating XPS.
