feat: implement module type resolution algorithm ESM_FILE_FORMAT from the spec (#535)

resolves #527
fixes #508

This PR adds a new `module_type` option and also to the returned result.

```ts
export interface NapiResolveOptions {
  /**
   * Resolve [ResolveResult::moduleType].
   *
   * Default `false`
   */
  moduleType?: boolean
}
```

```ts
export interface ResolveResult {
  /**
   * Module type for this path.
   *
   * The module type is computed `ESM_FILE_FORMAT` from the [ESM resolution algorithm specification](https://nodejs.org/docs/latest/api/esm.html#resolution-algorithm-specification).
   *
   *  The algorithm uses the file extension or finds the closest `package.json` with the `type` field.
   */
  moduleType?: ModuleType

}

export declare const enum ModuleType {
  Module = 'module',
  CommonJs = 'commonjs',
  Json = 'json',
  Wasm = 'wasm',
  Addon = 'addon'
}
```

Node.js will treat the following as [ES
modules](https://nodejs.org/api/esm.html):
* Files with an .mjs extension.
* Files with a .js extension when the nearest parent package.json file
contains a top-level ["type"](https://nodejs.org/api/packages.html#type)
field with a value of "module".
