Fix SageMaker processing stopped state handling

[Codingaditya17]

This PR fixes SageMakerProcessingOperator so that Processing jobs ending in the Stopped state are treated as failed terminal states when deferrable=True and wait_for_completion=True.

The operator was checking the generic SageMaker failed_states, which does not include Stopped. This updates it to use processing_job_failed_states and adds a unit test for the Stopped state before deferral.

Closes #67281

Tests:

• Not run locally: uv test environment failed while building jpype1 because Java runtime is not installed on my machine.

Thanks for the review. The only failing check appears to be Integration core otel, and the visible log only shows Process completed with exit code 1 without a traceback or failure related to the SageMaker provider changes in this PR.

This PR only touches SageMakerProcessingOperator and its unit test. Could a maintainer please re-run the failed integration job if possible?
