resource/aws_kms_grant: Retries read until principals return valid ARNs

[gdavison]

In some cases, there is a race condition with KMS Key Grants where an IAM unique id is returned instead of a valid principal ARN. Retry reading until the principals are valid. Previously, the state would not be updated.
