[dynamodb] Allow Resource Policy in DynamoDB tables

[shabbskagalwala]

Is your feature request related to a problem?
No.

It would be nice to have the ability to attach a Resource Policy to DynamoDB tables - similar to s3 bucket policies.

https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_PutResourcePolicy.html

Describe the solution you'd like

Add a field similar to the Table CRD Policy that would allow adding a resource policy to the dynamodb table.

Terraform equivalent: https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/dynamodb_resource_policy
