Problem

Certain usage patterns of functions end up with Caused By: ❌ Deployment failed: Error [ValidationError]: Circular dependency between resources:.

This happens is scenarios where it could have been avoided. Just because we pack all functions into same stack and therefore coupling them together.

Changes

This PR is a failed attempt to make auth and data a "donor" of stack/scope.

At some point I realized that such design will be deemed to fail in generic case.
I.e. it would create cyclic compile time problem, where writing an elegant code that would compile is just impossible.
See here.

This perhaps could be further explored by adding "post defineX" APIs. I.e. by exposing additional mutators on construct factories (like func.useScopeOf(data) or so).

Validation

There are two test projects used to reproduce the original problem:

  1. test-projects/function-stack-1
  2. test-projects/function-stack-2

Both deployed successfully with new setting.
