Part of https://github.com/apache/airflow/issues/51671
Refactor timeout functionality by moving `TimeoutPosix` class to the
`dagbag` module where it's primarily used, and remove windows timeout support
along the way as Airflow 3.0 no longer supports windows due to `fork()` usage.
Since this is the final set of usage in core, providers is handled by:
https://github.com/apache/airflow/pull/54183 and the class was moved to task
SDK in https://github.com/apache/airflow/pull/54089. I am deprecating this from
utils and asking dag authors to use it from sdk.
## Testing
- [x] Updated existing timeout tests to use new import path
- [x] Verified DAG import timeout functionality still works
- [x] Confirmed backward compatibility with `timeout` alias
Back compat:
