Menus: Remove .menu-item-has-children on wp_nav_menu last level menu items when $depth arg is used.

This changeset prevents `wp_nav_menu` last level menu items from having the `.menu-item-has-children` class when the `$depth` argument is used. It adds a loop in `wp_nav_menu()` to calculate the depth of each menu item with children to make sure the class is added only when applicable.

Fixes #28620.
