Add a public generate_cutting_experiments function

[caleb-johnson]

This should be the first PR to be merged into main based on #352 .

This creates a public function generate_cutting_experiments which largely mimics the current private function of the same name in cutting_evaluation.

Thanks -- I am still pondering some things, but this should be enough to get you started.

BTW, you might wonder at times why I seem attached to execute_experiments. The first reason is to maintain compatibility with existing workflows, but there is also a second (more important) reason: if in the future we want to provide advanced users the ability to do special things with their experiments (e.g., bin them by weight and then send multiple batches with different shots counts), then we're going to need something that looks a lot like execute_experiments, just with some additional knobs to tweak. Even then, we'll want to expose Qiskit Runtime's Sampler directly in the tutorials so that people gain intuition about how it is used. The execute_experiments function will then be a utility that enables more advanced use of Qiskit Runtime.

This is looking really good; I don't expect to have any further comments once we resolve the open threads.

Thanks, I am happy with this, modulo my one remaining comment.
