Damien George 9b090603a0 webassembly: Implement runPythonAsync() for top-level async code. ...

With this commit, `interpreter.runPythonAsync(code)` can now be used to run
Python code that uses `await` at the top level.  That will yield up to
JavaScript and produce a thenable, which the JavaScript runtime can then
resume.  Also implemented is the ability for Python code to await on
JavaScript promises/thenables.  For example, outer JavaScript code can
await on `runPythonAsync(code)` which then runs Python code that does
`await js.fetch(url)`.  The entire chain of calls will be suspended until
the fetch completes.
