[TC-DD-1.1] Add detailed instructions and verification criteria in TC-DD-1.1 script

[Ashwinigrl]

Summary Title:

Please describe the issue briefly in few words. Also please add the SVE event info (if applicable) Example: [SVE2] Test Harness fails to pair with a thread accessory.

Description:

The Python script for TC-DD-1.1 lacks sufficient guidance for ATL representatives during test execution. The current instructions are too generic and do not clearly outline the specific actions or expected outcomes for each step.

1. Several test steps do not specify what actions the ATL representative must perform.
2. Test steps orders in Test plan and Script are not matching
3. The script lacks detailed verification criteria and expected behavior for some steps, making it difficult to validate results accurately.

Expected Behavior:

1. The script should include clear, step-by-step execution guidance for ATL representatives.
2. Each step should specify expected values, responses, or observable outcomes to assist in accurate verification.
3. Additional comments or log messages should be added in the script to guide test execution and improve readability.

In the TC-DD-1.1 test plan

there's an extra step at the end, step 3.

Step3  |  Verify the packed binary data structure  |  Verify the packed binary data structure is padded with '0' bits at the end of the structure to the nearest byte boundary.

This step isn't currently implemented in the script. Please advise on how to implement this step, or, if the script is the source of truth, then to remove the step from the test plan.
