Apache Airflow Common Compatibility Provider

The `apache-airflow-providers-common-compat` package provides a compatibility layer for Apache Airflow, enabling seamless migration from Airflow 2 to Airflow 3. It utilizes lazy imports that first attempt Airflow 3 paths and then fall back to Airflow 2 paths, abstracting away version differences. This provider aims to centralize and replace scattered version-specific conditional imports within other Airflow providers. The current version is 1.14.2, and Airflow providers generally follow independent release cadences, adhering to SemVer.
