fix(stepfunctions-tasks): fix the generated IAM policy for EFS operat…

…ions (#30896)

### Issue # (if applicable)

Closes #30862.

### Reason for this change
Per [TagResource](https://docs.aws.amazon.com/efs/latest/ug/API_TagResource.html), the operation requires permissions for the `elasticfilesystem:TagResource` action. Also per [AWS managed policies for Amazon EFS](https://docs.aws.amazon.com/efs/latest/ug/security-iam-awsmanpol.html), all the `Action`(s) are prefixed with `elasticfilesystem:` (not `efs`).

### Description of changes
Updates the `iamServiceMap` that maintains list of services having mapping to IAM policy prefix names.

### Description of how you validated changes
Added unit test and integration test (along with snapshot).
