Add maxItems to QueryEnhancedRequest to simplify pagination

### Describe the feature

Add a direct method (e.g., maxItems() or limit()) to the QueryEnhancedRequest.Builder class in AWS SDK for Java v2 to control the maximum number of items returned in query results.

### Use Case

Currently, developers must implement complex pagination logic using iterators and page size controls to limit result sets, which adds unnecessary complexity to simple use cases. This feature would provide functionality similar to the `--max-items` parameter available in the AWS CLI for DynamoDB queries.
