Remove old lineage stuff

[uranusjr]

Body

We had some experiemental lineage classes in airflow.lineage. Those never caught on, and are not relevant anymore now that we have assets and trasparent OpenLineage support via AIP-62. We should remove the old stuff in 3.0, and put up a deprecation warning in 2.11 if not already.

Hi, I have a few questions while working on this issue:

• The compatibility module (airflow.providers.common.compat.lineage) still imports the airflow.lineage module. Does this mean I should move airflow.lineage to airflow.providers.common.compat.lineage instead of simply deleting it?
• For other airflow modules that import airflow.lineage, can all logic involving lineage be removed?

Thanks !
