Support ES modules

The runtime currently handles commonjs modules - and if an import statement is encountered the application will crash.

The implementation is currently in ModuleInternal.mm

It would be awesome if es modules were supported, since v8 already supports them - we are just missing the implementation for loading them (same-ish logic as for commonjs)

A reduced example for supporting es modules: https://stackoverflow.com/a/52031275/2270725

The gist of it is - we have to call ScriptCompiler::CompileModule on the source

Local<Module> module;
if (!ScriptCompiler::CompileModule(isolate, &source).ToLocal(&module)) {
  // if you have a v8::TryCatch, you should check it here.
  return;
}

Unresolved questions:

• Can the runtime support both types and interop between them?

Commencez dans ModuleInternal.mm en retraçant le chemin de chargement commonjs existant et comparez-le avec l’exemple fourni ScriptCompiler::CompileModule. Étudiez comment le chargement des modules V8 et l’interopérabilité avec commonjs devraient fonctionner. Le travail est terminé lorsque les instructions d’importation ne provoquent plus de plantage et que l’environnement d’exécution prend en charge l’interaction prévue entre les deux types de modules.
