Subject: Add debug operator for QPrinterInfo.

Add formatting helper to private class QPrintDevice and
use that to implement debug operators for QPrintDevice and QPrinterInfo.

Sample output:
(QPrinterInfo(id="HP_Color_LaserJet_CM6030_MFP", state=0, name="HP Color LaserJet CM6030 MFP", makeAndModel="HP Color LaserJet CM6030 MFP Postscript (recommended)", default, defaultPageSize=QPageSize("Letter", "Letter", 612x792pt, 2), supportsCustomPageSizes, physicalPageSize=(278, 396)..(907, 1296), defaultResolution=600, defaultDuplexMode=0, defaultColorMode=1, supportedMimeTypes=( "application/pdf" "application/postscript" "image/gif" "image/png" "image/jpeg" "image/tiff" "text/html" "text/plain")))

Task-number: QTBUG-44991
