(gen2-migration) `predictions` category

### Is this feature request related to a new or existing Amplify category?

_No response_

### Is this related to another service?

_No response_

### Describe the feature you'd like to request

Add support to the migration tool for the [predictions category](https://docs.amplify.aws/gen1/javascript/build-a-backend/more-features/predictions/). This includes both code generation and refactor.

### Describe the solution you'd like

We are going to use [cdk-from-cfn](https://github.com/cdklabs/cdk-from-cfn) in order to generate CDK code that we will then hookup into the amplify backend using `backend.createStack('predictions')`.

### Describe alternatives you've considered

None

### Additional context

This is how amplify recommends setting up predictions in Gen2 manually: https://docs.amplify.aws/react/build-a-backend/add-aws-services/predictions/

We can use as reference to review the cdk-from-cfn generated code.
