…ws#28718)

Currently, Amazon.CDK.AWS.Apigatewayv2 lacks support for AWS option as the [IntegrationType](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigatewayv2-integration.html#cfn-apigatewayv2-integration-integrationtype) for WebSocket Apigateway.

Added the capability that allows user to create a WebSocket Apigateway that calls directly other AWS services without a Lambda function middleware.

Closes aws#27164.
