CloudFormation::WaitCondition - Enhancement - Create resources after delete

### Name of the resource

AWS::CloudFormation::WaitCondition

### Resource name

_No response_

### Description

This FR is to add support for waiting to create a resource only after another has been deleted.

This would be helpful when we are reorganising or rationalise our CF template repos, without having to execute a stack termination and then creation.

### Other Details

N/A

The issue names AWS::CloudFormation::WaitCondition but mentions no repository files, tests, or entry points. Start by identifying where CloudFormation resource behavior and dependency ordering are documented or implemented; done means supporting creation of a resource only after another resource has been deleted, without terminating and recreating the stack.
