Bug 1659340, hide menu options if new print UI pref is enabled r=mstriemer

If print.tab_modal.enabled is enabled, we should not display the print preview
menu item, as this will redirect us to the print preview automatically and thus
be redundant with the other print button. We also want to hide the page setup
menu item.
