### Feature description

AWS lambda has [support for reporting partial batch failure for a SQS batch](https://docs.aws.amazon.com/lambda/latest/dg/with-sqs.html#services-sqs-batchfailurereporting). We're currently using it for our lambda functions on our [serverless.yml](https://www.serverless.com/blog/improved-sqs-batch-error-handling-with-aws-lambda), and would like to test the configuration locally. It'd be great to have it supported on LocalStack.
