#14469: Fix _repr_ of graphics objects

Graphical output of plots (or other graphics objects) is hooked into
`_repr_()`. Obviously, Python doesn't expect `repr` to have side effects
so we get fun stuff like
{{{
sage: g = Graphics()
sage: g?
}}}
showing a plot in addition to the help.
This patch moves the decision logic into the displayhook, and makes `repr`
always return a string representation as it should.
Also, deprecate the `show_output()` function. Wat?
