When moving services injected from the constructor to the controller arguments, I noticed a bug.

We were auto wiring an env var to a backed enum like this:

```php
class Foo
{
    public function __construct(
        #[Autowire(env: 'enum:App\Enum:SOME_ENV_KEY')]
        private \App\Enum $someEnum,
    ) {}

    public function __invoke() {}
}
```

This works fine with normal Symfony Dependency Injection.

But when we switch to controller arguments like this:
```php
class Foo
{
    public function __invoke(
        #[Autowire(env: 'enum:App\Enum:SOME_ENV_KEY')]
        \App\Enum $someEnum,
    ) {}
}
```

This stops working.

The issue is that BackedEnum's are excluded. But this should only be excluded when there is no Autowire attribute.
