provider/aws: Updating CloudFront distribution to set LoggingConfig i…

…f disabled (#6407)

- Addresses the issue when local state file has logging_config populated and the user
  disables the configuration via the UI (or in this case an
  application of the TF config).  This will now properly set the
  logging_config during the read operation and identify the state as
  diverging

Fixes #6390
