printers: Use AdwWindowTitle in some dialogs

If the printer name is long, the window title might get ellipsized more easily, specially in PpOptionsDialog, where the word "Details" can get longer in different translations. PpJobsDialog already use AdwWindowTitle for the same reason, so use it in PpOptionsDialog and PpDetailsDialog to keep consistency.

Also, add AdwDialog:title so Orca will announce the dialog names, specially in PpJobsDialog, which is using AdwWindowTitle without AdwDialog:title.
