Investigate usage of `utils` functions from Airflow core in Providers

Provider's have a lot of references of `utils` imports in them. Investigate that and remove those to remove `airflow-core` dependency on providers, this can be done either by:

1. If the util function is small-ish, consider moving it inside as a private function / class in provider itself while handling compat
2. If it can be consumed from task-sdk (if present in sdk), do that
