This patch extends `LoadEnvironment` to support loading ES modules,
and adds the following new types:
```cpp
enum class ModuleFormat : uint8_t {
kCommonJS,
kModule,
};
// Data for specifying an entry point script for LoadEnvironment().
// This class uses an opaque layout to allow future additions without
// breaking ABI. Use the setter methods to configure the entry point.
class ModuleData {
void set_source(std::string_view source);
void set_format(ModuleFormat format);
void set_resource_name(std::string_view name);
std::string_view source() const;
ModuleFormat format() const;
std::string_view resource_name() const;
};
class StartExecutionCallbackInfoWithModule {
void set_env(Environment* env);
void set_process_object(v8::Local<v8::Object> process_object);
void set_native_require(v8::Local<v8::Function> native_require);
void set_run_module(v8::Local<v8::Function> run_module);
void set_data(void* data);
Environment* env();
v8::Local<v8::Object> process();
v8::Local<v8::Function> native_require();
v8::Local<v8::Function> run_module();
void* data();
};
```
And two new `LoadEnvironment()` overloads:
```cpp
// Run entry point with ModuleData configuration
MaybeLocal<Value> LoadEnvironment(
Environment* env,
const ModuleData* entry_point,
EmbedderPreloadCallback preload = nullptr);
// Callback-based with new StartExecutionCallbackInfoWithModule
MaybeLocal<Value> LoadEnvironment(
Environment* env,
StartExecutionCallbackWithModule cb,
EmbedderPreloadCallback preload = nullptr,
void* callback_data = nullptr);
```
