[nautilus] editorconfig: Create initial files

    editorconfig: Create initial files
    
    Borrow .editorconfig files from the GTK project.  Use the exact
    same file for src/gtk since we are still keeping GTK style there
    (remove root=true since it's no longer in the root).
    
    The root .editorconfig file is slightly modified since we use
    4 space tabs.  Leave tab_width=8 since we do have tabs in the code.
    
    See: https://editorconfig.org/
