[ AWS::Cloudformation::Stack ] Support for custom-named NestedStacks

### Name of the resource

AWS::CloudFormation::Stack

### Resource name

_No response_

### Description

Currently, it seems that there is no way to apply custom naming conventions to NestedStacks. They default to the following convention: ```{ParentStackName}-{LogicalId}-{GUID}```

The [StackName](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-cloudformation-stack.html#cfn-cloudformation-stack-stackname) is documented, and found in the resource type's schema:

Upon deployment, the parent stack fails to create NestedStack with:
```Encountered unsupported property StackName```

**Kindly consider allowing customized NestedStack names**

**Schema**
```aws cloudformation describe-type --type-name AWS::CloudFormation::Stack --type RESOURCE --output json > aws-cloudformation-stack.json```

### Other Details

_No response_

No repository files or tests are named in the issue. Start by reviewing the AWS::CloudFormation::Stack schema, the documented StackName property, and the supplied aws cloudformation describe-type command; done means the requested custom naming behavior for nested stacks is supported and the unsupported-property failure is resolved.
