…GH-136931) Basic support for pyrepl in Emscripten. Limitations: * requires JSPI * no signal handling implemented As followup work, it would be nice to implement a webworker variant for when JSPI is not available and proper signal handling. Because it requires JSPI, it doesn't work in Safari. Firefox requires setting an experimental flag. All the Chromiums have full support since May. Until we make it work without JSPI, let's keep the original web_example around.

Because it requires JSPI, it doesn't work in Safari. Firefox requires setting an experimental flag. All the Chromiums have full support since May. Until we make it work without JSPI, let's keep the original web_example around.
