Closes #32470 ### Reason for this change Some customers have reported seeing the error `TypeError: localAspects is not iterable` upon upgrading to CDK v2.172.0 (this is when the Priority-ordered aspects feature was released). This is likely caused by customers having dependencies on third-party constructs/libraries which are using outdated versions (< 2.172.0) of CDK. The problem more specifically is that the `Aspects.applied` function was added in v2.172.0, and the new `invokeAspects` function calls this function on all nodes in the tree. ### Description of changes Created a workaround for customers. Added the `getAspectApplications` function in `synthesis.ts` - this function creates `AspectApplication` objects from `Aspects.all` if `Aspects.applied` does not exist. ### Describe any new or updated permissions being added None. ### Description of how you validated changes New unit test in `aspect.test.ts` with a monkey patched `Aspects.applied` function. ### Checklist - [x] My code adheres to the [CONTRIBUTING GUIDE](https://github.com/aws/aws-cdk/blob/main/CONTRIBUTING.md) and [DESIGN GUIDELINES](https://github.com/aws/aws-cdk/blob/main/docs/DESIGN_GUIDELINES.md) ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license*
