Update int test to receive access context manager policy rather than create + destroy

[bharathkkb]

TL;DR

We do a few clean ups between tests like https://github.com/terraform-google-modules/terraform-google-vpc-service-controls/blob/0d94f375b9e4aa98d830b02e53b34cc83c79075b/build/int.cloudbuild.yaml#L26that can result in the access context manager policy not existing. It would be better to skip testing the main root module as it is a single resource without any logic and instead receive a static policy as a var for testing other more complex submodules.

Looks like this is also breaking the terraform-example-foundation test
