[AIRFLOW-4759] Batch queries in set_state API. (#5403)
Setting a `dagrun` to success or failure calls set_state for each task in
the dag, running multiple database queries for each one. We can reduce
the number of queries, and improve performance for the associated
endpoints, by setting the states of all relevant tasks in the same query.
