Support "UsePreviousValue" in parameterOverrides / parameters in CodePipeline Action

### Description

In other tools/apis it's possible to use the previous value of parameters in CloudFormation templates, e.g.

`aws cloudformation update-stack --stack-name asg-xxx-123 --use-previous-template --parameters ParameterKey=ApplicationName,UsePreviousValue=true`

or in the deploy cli (which is maybe more like the cloudformation codepipeline action) it's handled automatically since this PR: https://github.com/aws/aws-cli/pull/2573

In the api reference of CloudFormation this option is also documented: https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_Parameter.html

Only in the [CodePipeline CloudFormation action](https://docs.aws.amazon.com/codepipeline/latest/userguide/action-reference-CloudFormation.html) there is no way to use the previous value of the parameter. Without this option the current value is overridden at deploy time with the `default` one. Please provide a way to use the the previous value without defining a new value for a parameter.

I still don‘t know if this is a bug or feature request.

Thanks in advance!

### Other Details

_No response_

Start by comparing the CodePipeline CloudFormation action reference with the CloudFormation Parameter API and the aws cloudformation update-stack example linked in the issue. Done means the action provides a documented way to preserve a parameter's previous value without supplying a new value.
