Recurring SQS Redrive rule on eventbridge DLQ

**What were you trying to accomplish?**

Validate an EventBridge component. I got a rule violation that said I needed a RedrivePolicy on my DLQ attached to my Eventbridge's targets.

## Expected Behavior
If a SQS queue is already configured as a DLQ for Eventbridge's target, don't run the rule on the DLQ.

## Current Behavior

## Possible Solution
Same thing as [PR#82](https://github.com/awslabs/serverless-rules/pull/82) but handle DLQ on Eventbridge component.

## Environment

* **Infrastructure as code technology used**:
* **(for `cfn-lint`) Python, cfn-lint, and cfn-lint-serverless versions**: cfn-lint 0.59.0 cfn-lint-serverless 0.3.2
* **(for `tflint`) Go, tflint versions**:
* **Debugging logs**

Start by reviewing PR#82 and the EventBridge rule implementation, then trace how SQS dead-letter queues are identified for EventBridge targets. Confirm the existing cfn-lint-serverless rule behavior with an EventBridge template containing an SQS DLQ; done means that configured DLQs are excluded from the RedrivePolicy violation.
