QPrinter: Add Current Page print range support

Support the selection of Current Page option in the print dialog by
activating a new QPrintDialog::PrintDialogOption.  If selected the
PrintRange is set to CurrentPage.

It is the responsibility of the application to read the PrintRange and
apply the Current Page selection when rendering the pages.
