AIP-72: Semantically correct the TI state handling in supervisor

[amoghrajesh]

We transition states to a terminal state in supervisor under wait(). We do it when the task has finished running and has reached a "non direct" state. Direct states are ones which need some information to transition into. For example, the reschedule state needs "reschedule date".

Code that handles this: https://github.com/apache/airflow/blob/main/task_sdk/src/airflow/sdk/execution_time/supervisor.py#L524-L527

However, a more semantically correct way to transition into a terminal state would be to check if "hey, have we already transitioned our TI into some state, if not, let me do it - to success or failed or something like that."

This PR corrects some of these things semantically so that it reflects the intent.
Checks for if self.final_state not in STATES_SENT_DIRECTLY
