SIC: QPrintSupport - Remove options api from QPageSetupDialog

QPageSetupDialog has an enum PageSetupDialogOption, however one option
had support removed in Qt 4.5 and the remaining 2 are actually for an
internal implementation detail that could lead to memory leaks if
changed by an app.

This change removes the enum and the api as they is now useless.
