Improve executor callback log file template #60464
Description
Split from PR #60435.
In airflow-core/src/airflow/executors/workloads.py (ExecuteCallback.make), there is a TODO: # TODO: better log file template.
Current log path: executor_callbacks/{callback.id}.
Consider a hierarchical path (e.g. callbacks/{dag_id}/{run_id}/{callback_id}) to make logs easier to locate.
