[Routing] Simplify importing routes defined on controller services

Fine-tuning #61492

Before:

```yaml
controllers:
    resource: attributes
    type: tagged_services
```

After:

```yaml
controllers:
    resource: routing.controllers
```

And when using `MicroKernelTrait` (the default recipe), there's nothing to configure to have routes loaded from `#[Route]` attributes:

```yaml
#config/routes.yaml
# the file can be just empty from any config, and only have a comment saying what it's for
```

```php
// config/routes.php
return Routes::config([
]);
```

The way to opt-out from this `routing.controllers` import would be to override the `Kernel::configureRoutes()` method.
