The file dialog allows to move the file name labels from next to the
icon to right under the icon for Short View. However, having to go in
a deeply nested Settings button → Icon Position → Above File Name
submenu makes it both hard to discover and cumbersome to use. Ideally
this setting could be accessed directly from the menu for good usability.
Making it easy to change back settings is especially important in light
of D12326, which will enable Icons Above File Name by default.
We linearize the submenu entries from the submenu to the top-level menu,
which works just fine as there are only two entries, increasing the
overall menu size by only one item while removing an entire submenu.
While the submenu itself is not advertised in the API docs, it was
publicly accessible, and therefore is kept for compatiblity reasons
(although with a slight change in wording).
