Provide an interceptable way to handle unhandled exceptions on JS

[qwwdfsad]

Currently, all unhandled exceptions go straight to console.onError, which is not desirable for enterprise applications, where more thoughtful and granular exception handling is typically required.

The proposed solution is to use window.onError for browser environments and uncaughtException for Node.js

Expected solution for browser:

  fun handleCoroutineExceptionImpl(context, exception) { 
    window.dispatchEvent(ErrorEvent("error", ErrorEventInit { error = exception }));
  }
