    filechoosernative: Implement gtk_file_chooser_set_filter()
    
    gtk_file_chooser_set_filter() doesn't work for GtkFileChooserNative
    
    The code forwards added and removed filters to the delegate dialog, but
    doesn't do anything to set the selected one, so the wrong one gets
    chosen. So let's do that.
    
    Note this only fixes the fallback dialog. It doesn't fix the portal,
    because the portal doesn't support this yet.
    
    Partial fix for #1492
