Remove old Tools/demo/ scripts #97681

I proposed to remove outdated example scripts: issue #97669. In the related discussion https://discuss.python.org/t/remove-outdated-tools-scripts-scripts/19571 @gvanrossum proposed to remove demos of Tools/demos/.

@gvanrossum:

I think we should remove everything from those directories that isn’t needed to build. I don’t know how to tell what that is. For sure the Tools/demo directory can go – there’s even a demo of remote execution there! :-)

These demo scripts are not installed by make install.

The remote execution are the rpython.py + rpythond.py scripts:

Remote python client. Execute Python commands remotely and send output back.

There is no security in these scripts: the TCP communication is not encrypted and there is no authentication.

Tools/demo/README describes the demo scripts.

Note: the stdlib contains the turledemo module: https://docs.python.org/dev/library/turtle.html#module-turtledemo
