Fix exported type resolution in commonjs (#24495)

* Fix resolution of exported types in commonjs

It is fine to resolve the types of exported classes in ES6:

```js
export class C {
}
var c = new C()
```

But not for commonjs exported classes:

```js
module.exports.C = class {
}
var c = new C() // should error
```

Fixes #24492

* All jsdoc type aliases are available locally in commonjs modules

* Check that location isSourceFile before commonJsModuleIndicator
