windows: Exceptions from asynchronous functions are not thrown correctly

[ahaoboy]

Only synchronous exceptions are caught and displayed.
The following code fails to execute without any error message

async function main() {
  throw new Error()
}

main()

This is currently a limitation in the QuickJS engine. We are able to capture unhandled promise rejections but that doesn't align with how it's handled in Node.js. We'll be working on a patch for this.
