fix(cli): support attributes of DynamoDB Tables for hotswapping (#19620)

When using Nested Stacks, Parameters are used to pass values between the parent and child Stacks.
A customer had a setup where a DynamoDB Table was in the parent Stack,
and a Lambda using that Table (through environment variables) was in the child Stack.
In order to be able to hotswap the Lambda in the child Stack,
we have to correctly resolve attributes of the `AWS::DynamoDB::Table` resource,
like `Ref` and `Arn`, to resolve the values of the Parameters passed to the child Stack.

Fixes #19421
