Title: DOC: `axis_off` wrongfuly appears as a parameter to Figure.add_subplot

`axis_off` and `axis_on` appear as parameters on Figure.add_subplot,
and anywhere %(Axes)s is used. The introspection picks them up
because they have setters: `_BaseAxes.set_axis_off()`,
but they do not accept any argument and therefore cannot be passed as parameters.
