Bug: SAM Doesn't recognize changes related to intrinsic functions (#6610)

See also #6610

I am trying to redeploy a stack using values resolved from secrets manager:
```
- Name: API_KEY
Value: '{{resolve:secretsmanager:my-app-api-key:SecretString}}'
```
sam reports `Error: No changes to deploy. Stack stack is up to date`. There should be a mechanism to redeploy a stack even if the template has not changed, because the resolved values might have changed.
Whether this is CF functionality or not is irrelevant if I only use SAM CLI.
