Support applying account-level data protection policy to all log groups in an account via CFN

### Name of the resource

### Resource name

AWS::Logs::<>

### Description

Account-level data protection policy feature of CloudWatch was announced just recently on: Jun 8, 2023:
https://aws.amazon.com/about-aws/whats-new/2023/06/amazon-cloudwatch-logs-data-protection-policy-configuration/

While there is a way in CFN to set data protection policy for a single log group using the "DataProtectionPolicy" property of resource: AWS::Logs::LogGroup, there seems to be no way currently to set this policy on account-level via CFN, as is possible via Cloudwatch Console, CLI and API.

This request is to support the above feature in CloudFormation.

### Other Details

_No response_

No repository files, tests, or entry points are identified. Start by reviewing the CloudFormation coverage roadmap conventions and the linked CloudWatch account-level data protection policy announcement, then compare the console, CLI, and API behavior with the existing AWS::Logs::LogGroup DataProtectionPolicy support. Done means account-level policy configuration is available through CloudFormation.
