Typing order error with generic and specific import order

We've been facing quite the head scratcher over at the Lime discord... Lime has a dependency chain involving a generic type that can be roughly simplified to this sample: https://try.haxe.org/#763D572a

Main.hx:
```haxe
import Generic;

class Main {
public function new() {
final generic = new Generic();
}

static function main() {}
}
```

Generic.hx:
```haxe
var main = new Main();

@:generic
class Generic {
public function new() {
trace(main);
}
}
```

This results in the error:
```
[ERROR] Generic.hx:5: lines 5-7

5 | public function new() {
6 | trace(main);
7 | }
|
| Field new has no expression (possible typing order issue)

[ERROR] Main.hx:5: characters 23-35

5 | final generic = new Generic();
| ^^^^^^^^^^^^
| While building Generic_Int
```

Removing the `@:generic` meta avoids the issue https://github.com/openfl/lime/pull/1662. In Lime's case, moving around types and simplifying certain dependency chains sometimes fixes the issue, but it's quite a fragile solution. In this example, removing the `import Generic;` at the top of Main.hx avoids the error somehow as well...
