[gtk/listview-for-merge: 146/174] columnview: Add GtkColumnViewCell

commit e9d27798744daaec03beb17a574c42aa81db9f27
Author: Benjamin Otte <otte redhat com>
Date:   Sat Nov 2 06:15:38 2019 +0100

    columnview: Add GtkColumnViewCell
    
    It's a GtkListItemWidget subclass that tracks the column it belongs to
    and allows the column to track it.
    
    We also use this subclass to implement sizing support so columns share
    the same size and get resized in sync.
