Now MappedOperator in core is entirely detached from the SDK. I decided to remove the start_from_trigger code entirely (the code path is already entirely unreachable in Airflow 3) since it causes too many Mypy errors. We can always get the implementation back from Git history when we re-implement the feature with the new task runner.

Now MappedOperator in core is entirely detached from the SDK.
I decided to remove the start_from_trigger code entirely from MappedOperator (the code path is already entirely unreachable in Airflow 3, see referenced snippet below) since it causes too many Mypy errors.
