Add README Pipeline Status for Huawei Ascend NPU

[xuedinge233]

Hello! Following the merge of #6445, I have implemented a CI pipeline to validate the Huawei Ascend NPU.

Summary

Implemented CI for the Huawei Ascend NPU to automate unit testing and synchronize test results in the Pipeline Status tables.

Motivation

While the Huawei Ascend NPU usage documentation has been updated, there is a lack of clarity regarding the operational process.

Implementation

The CI process includes the following steps:

• Set CI triggers for daily scheduled runs and upon receiving pull requests.
• Use ascendai/cann Docker image to run the basic lift environment.
• Install the necessary libraries for PyTorch and DeepSpeed, and verify the environment post-installation.
• Execute test files, including accelerator autotuning, located in tests/unit for unit testing.
• Update the README.md with the latest test results.
