Don't add processor to all loggers if tags specify a channel or handler

Similar to symfony/symfony#61526.

When you add a custom processor to a specific channel or handler, it gets added to **all** channels because `ProcessorInterface` is [registered for autoconfiguration](https://github.com/symfony/monolog-bundle/blob/58b98dcf5d3c818679f078d514284b16cc986d34/DependencyInjection/MonologExtension.php#L106-L108).

Here's a simple example:

```php
#[AsMonologProcessor('my_channel')]
final class MyProcessor implements ProcessorInterface
{
    public function __invoke(LogRecord $record) {}
}
```

You'd expect this processor to be registered only for `my_channel`, but due to autoconfiguration it's added to every channel.

The workaround is to disable autoconfiguration and add an explicit tag.

```yaml
services:
    App\MyProcessor:
        autoconfigure: false
        tags:
            - monolog.processor: { channel: 'my_channel' }
```

This PR ensures a processor is not added to all channels when an explicit channel or handler is configured.
