Show hierarchy in Pages box on Menus screen

[jane]

If you View All on the Menus screen, it lists all pages but has them in alphabetical order rather than showing nesting/hierarchy like it does on edit.php?post_type=page (or in categories box on post editor). For sites with a lot of pages, having to remember/recreate the hierarchy in the menu is a pain in the butt. It would nice for the View All view for Pages (and custom post types with hierarchy) to display as they do in the regular pages list on edit.php?post_type=page instead of alphabetically.

Decided to close #14660 as a duplicate. There's also #14180 for hierarchical taxonomies.

Whoops. I'll take ownership of this one, too, though.
