QPrinterInfo - Switch to QPlatformPrintDevice

Change the QPrinterInfo implementation to use QPlatformPrintDevice as
the backend.  Remove all the old QPrinterInfo related code from the
QPA plugin.  Add public api to QPrinterInfo to support some features
from QPlatformPrintDevice.

[ChangeLog][QtPrintSupport][QPrinterInfo] Added new public api for
isRemote(), state(), defaultPageSize(), supportedPageSizes(),
supportsCustomPageSizes(), minimumPhysicalPageSize(),
maximumPhysicalPageSize(), supportedResolutions(),
availablePrinterNames(), and defaultPrinterName(). The use of
availablePrinters() is discouraged due to performance concerns.

Task-number: QTBUG-35248
