(backups): Backup vault cannot be deleted because it contains recovery points

### Describe the feature

Provide a `force_delete` option to destroy all recovery points in an AWS Backup Vault.

Terraform has a feature for [this](https://github.com/hashicorp/terraform-provider-aws/issues/13247) for a few years.

This would resolve

```json
{
"errorCode": "InvalidRequestException",
"errorMessage": "Backup vault cannot be deleted because it contains recovery points.",
"requestParameters": {
"backupVaultName": ""
}
}
```

### Use Case

Similar to s3 `delete_objects` to delete all bucket objects when a bucket is deleted, the same should be provided for AWS Backup Vaults (especially when working in ephemeral environments).

Currently, you need to manually [delete recovery points](https://docs.aws.amazon.com/aws-backup/latest/devguide/create-a-vault.html)

### Proposed Solution

Use a custom resource to delete all recovery points before the Backup Vault is deleted.

### Acknowledgements

- [ ] I may be able to implement this feature request
- [ ] This feature might incur a breaking change

### CDK version used

2.180.0

### Environment details (OS name and version, etc.)

Mac

The issue does not name files or tests. Start by locating the AWS Backup Vault construct and its deletion behavior, then review the AWS Backup APIs for listing and deleting recovery points. Done means a force_delete option removes the vault's recovery points before deletion without changing default behavior.
