(dynamodb): Tags not replicated when creating Table replicas

When creating a Global Table in DynamoDB with CDK, tags are not propagated to the replication regions and there is no ability to define tags for those replication regions. As a result, our resources are remediated by internal tools due to missing tags.

### Reproduction Steps

When creating a Global Table via CDK, I add the following prop to my Table Construct:
`replicationRegions: ["us-east-2"]`

Additionally, I have tags defined for the whole the stack:
`new AppStack(app, 'DigitalAccountDynamoStack', { tags: { ['deployment_guid']: process.env.bamboo_forge_deployment_guid as string, }});`

I have also tried:
`Tags.of(app).add('deployment_guid', process.env.bamboo_forge_deployment_guid as string);`
As well as:
`Tag.add(appStack, 'deployment_guid', process.env.bamboo_forge_deployment_guid as string);`

All result in the same: missing tags.

### What did you expect to happen?

Tags from the core region should be replicated to the replication regions or there should be a property to manually set the tags.

### What actually happened?

Tags are empty in replication regions.

### Environment

- **CDK CLI Version :**1.106.1
- **Framework Version:**
- **Node.js Version:**14.6.0
- **OS :**Mac OS
- **Language (Version):** TypeScript

This is :bug: Bug Report

Start by reproducing the issue with a CDK DynamoDB Table using replicationRegions and stack-level tags, then trace the Table construct's replica handling. Done means tags are propagated to replication regions or a documented property allows setting replica tags, with tests covering the reported configuration.
