Enable TCH004 and TCH005 rules

[Taragolis]

Follow-up: #35465 (comment)

Enable two additional rules TCH rules in ruff

1. TCH004 - Check that import only use as type annotation, has false positive alarms so I think that is why it under the --unsafe-fixes

airflow/dag_processing/processor.py:66:36: TCH004 Move import `airflow.models.dag.DAG` out of type-checking block. Import is used for more than type hinting.
airflow/serialization/pydantic/job.py:27:34: TCH004 Move import `airflow.jobs.job.Job` out of type-checking block. Import is used for more than type hinting.

2. TCH005 - Remove empty TYPE_CHECKING block

Move to draft for prevent accidentally merge into the main

Nice.

[Taragolis]

Need to check that nothing actually broken after this changes.

But seems like it should fix some methods in:

• airflow/dag_processing/processor.py
• airflow/serialization/pydantic/job.py

[Taragolis]

Yeah.. Circular imports

ImportError: cannot import name 'Job' from partially initialized module 'airflow.jobs.job' (most likely due to a circular import) (/opt/airflow/airflow/jobs/job.py)

Well local imports then

[Taragolis]

The real dark magic happen here

airflow/airflow/serialization/serialized_objects.py

Lines 446 to 448 in 64a64ab

	elif var.__class__.__name__ == "V1Pod" and _has_kubernetes() and isinstance(var, k8s.V1Pod):
	json_pod = PodGenerator.serialize_pod(var)
	return cls._encode(json_pod, type_=DAT.POD)

That is only affect k8s and PodGenerator so better exclude only this lines from check rather then entire module
