gui: Remove show/hide selection option in lists

The implementation of the "show_selection_marker" option in
lists isn't great. It's a cosmetic option used to hide the
selection, but it causes the list to do funny things to the
selected_item and doesn't play nice with voiced menus, since
these rely on the selection to determine what item is spoken.

There are only two user-facing lists that use the option, the
"Rockbox Info" screen and a menu in the superdom plugin. The
rest are debug screens, and cosmetics don't matter much there.

Given how little used the option is, and its issues, removing
it seems reasonable.
