### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

Localstack always bypasses SNS message attributes to SQS message attributes, while AWS does it only when `raw_message_delivery` is enabled. See https://stackoverflow.com/questions/44238656/how-to-add-sqs-message-attributes-in-sns-subscription

### Expected Behavior

SNS message attributes bypassed to SQS message attribute only when `raw_message_delivery` is `true`.

### How are you starting LocalStack?

With a `docker run` command

### Steps To Reproduce

Try to send SNS message with attributes in Localstack and in AWS.
AWS will not map SNS message attributes to SQS message attributes without `raw_message_delivery = true` parameter for a topic subscription.

### Environment

```markdown
- OS: docker
- LocalStack: latest
```
