Window to Tab string change

 Bug: 5145162
 Part of this also involved unifying the wording between tablet and
 phones menu, which revealed some unused assets. Combined bookmark
 phone and tablet menus into one xml, with bool switches to turn
 items on/off as needed instead of having 2 very similar files
