Menus: Selected display locations for new menus aren't saved

[dlh]

[48051] provided the ability to adjust menu settings when creating a menu on nav-menus.php. [50938] later corrected some issues with the "Display location" setting specifically. Now, however, when creating a menu, the selected menu locations aren't saved at all.

This behavior should be replicable on a fresh installation using Twenty Twenty-One by visiting Appearance > Menus, giving your first menu a name, selecting a location or two, and saving. The menu will save, but the locations won't.

The linked PR attempts to address the issue by assigning only the locations in $_POST['menu-locations'] to the new menu.
