Investigate potential uses of the WASI build of CPython

[cwebster-99]

Now that the WASI build of Python is finished, we should investigate its best uses. An initial brainstorm has resulted in the following ideas:

• Runtime in the browser (full browser support)
• Extension for users that don't have Python installed (lightweight version of the extension for prototyping on desktop)
• Enabling writing whole Python extension in Python --> environment discovery
• Better working with tools extensions

We need to do more customer discovery and benchmarking to discover the best and more realistic use cases.
