[gtk/inspector-list-model: 2/4] inspector: Rename DataList -> TreeData

commit 52666d6fe5a78de911133ca55856ee4ec48e7ba9
Author: Matthias Clasen <mclasen redhat com>
Date:   Tue Jun 30 15:17:14 2020 -0400

    inspector: Rename DataList -> TreeData
    
    Rename the DataList object to TreeData, in preparation
    for adding a ListData object for list models. While
    we are touching it, modernize it a bit (drop the Private
    struct, use a layout manager, etc).
