Dags that start an EMR Serverless interactive session need a way to end it as soon as their work is done rather than relying on the session's idle timeout. Stopping follows the same rules as starting: completion waiting decides whether the task waits, deferrable mode only picks how it waits, and the triggerer polls with the task's region, SSL verification and botocore settings.

Add
EmrServerlessStopSessionOperator, which terminates an EMR Serverless interactive(Spark Connect) session and can wait until it reaches
TERMINATED.Why:
terminated or hit their idle timeout, so Dags need an explicit way to end a session
once their work is done.
Changes:
TerminateSessionboto3 API directly, after the samebotocore >= 1.43.0runtime check the other session operators use, so the provider'sdependency floor is unchanged.
EmrServerlessStopSessionTriggerand theserverless_session_terminatedwaiter supportsynchronous and deferrable waiting. As in
EmrServerlessStartSessionOperator,wait_for_completiondecides whether the task waits anddeferrableonly picks how,and the trigger polls with the task's region, SSL verification and botocore settings.
This completes the interactive session lifecycle started in #70763 (start) and #70766
(get endpoint). It replaces #70768, which the stale bot closed before it was reviewed.
