(apigatewayv2): Regression in 1.87.0

The changes in #12528 introduced a regression when having the following setup:

ApiStack -> ChildStack with Lambda, HttpRoute, etc

By moving the instantiation of the HttpIntegration class to the HttpApi. _addIntegration method the scope was changed from the Route to the HttpApi object. This leads to a cyclic reference in the architecture described above.

So starting with 1.87.0 all my ApiGateway applications no longer synthesize.

Environment

• Framework Version: 1.87.0
• Node.js Version: v14.15.4
• OS : macOS
• Language (Version): TS

Adding this dependency (myapp-backend-pipeline/myapp-backend-dev/Api/Config -> myapp-backend-pipeline/myapp-backend-dev/Api/Api/Resource/Resource.Ref) would create a cyclic reference.
