The Symfony Messenger component provides a SerializerInterface to encode/decode the `Envelope`, this can be used to improve the Interoperability (see [article from jolicode](https://jolicode.com/blog/symfony-messenger-et-linteroperabilite) (french))

Sadly, the current implementation of SQS adapter json_encode the elements of the `Envelope` (`string body` + `string[] headers`) and store everything in the SQS message `Body`. That partially defect the interoperability: 3rd party have to also wrap (unwrap) message form json_encoded Body.

This PR leverage the AWS SQS `Body` and `MessageAttribute` properties to store message information:

```yaml
# before
SQS Message:
  Body: {"body": "hello world", "headers": {"foo": "bar"}}
  MessageAttributes: {}

# after
SQS Message:
  Body: hello world
  MessageAttributes:
    foor: bar
```
