    list-view: Merge did_not_drag() into its caller
    
    This function has only one caller and it relies on the passed GdkEvent
    for everything.
    
    However, in GTK 4, we are going to depend less on GdkEvent and more on
    the gesture itself and its signal handler parameters.
    
    So, inline the function to make sure we have everything at ready for
    when we switch to GTK 4.
