[gtk/inspector-display: 2/6] inspector: Make visual settings respect the inspected display

commit bd1f7e057a3618ba71780615fee9a059034cf549
Author: Matthias Clasen <mclasen redhat com>

    inspector: Make visual settings respect the inspected display
    
    This is not quite complete, GTK and GSK debug flags
    are not per display, and slowdown and text direction
    are not either.
