[nautilus/wip/antoniof/flow-box-preparation: 66/68] general: Remove canvas view

[António Fernandes <antoniof src gnome org>]

commit 2d1deaac2dd12b0ba16446bfbf3498b266e60338
Author: António Fernandes <antoniof gnome org>

    general: Remove canvas view
    
    The new grid view has reached feature parity with the canvas, if we
    ignore drag-and-drop and clipboard support (which would need to be
    reimplemented in GTK 4 anyway) and performance scalability (which is
    a problem of GtkFlowBox and solvable by using GtkGridView in GTK 4).
    
    The canvas view relies on extensive custom implementation for layout,
    drawing, input handling, accessibility, etc., which would be too
    hard to port to in GT1K4.
    
    Furthermore, most of its features, such as support for manual sorting,
    haven't been used since the "icons on desktop" feature has been taken
    out from this app. We are actually using a swiss army knife for a job
    where we only need a single blade -- a simple pocketknife would do!
    
    Therefore, we say goodbye to this seasoned veteran widget, who has
    served us for 2 whole decades.
