[nautilus/wip/antoniof/column-chooser-dialog-rework: 9/10] column-chooser: Move some function definitions

[António Fernandes <antoniof src gnome org>]

commit 6ba74920e2b4b9da8959f7481d0c48d6a0eb75d4
Author: António Fernandes <antoniof gnome org>
Date:   Sun Jul 25 00:00:23 2021 +0100

    column-chooser: Move some function definitions
    
    It's more usual to find the ::class_init() definition near the end,
    and it avoids a large number of forwards declarations.
