Enable to cancel pipeline jobs during checkout code and tests (#12436)

co-authorized by: jianquanye@microsoft.com

Why I did it
Now, checkout code step and KVM test job can't be cancelled even though the whole build is cancelled.
That's because by using Azure Pipeline Conditions, we customized the running condition, and we need to react to the Cancel action explicitly by asserting 'succeeded'

How I did it
Assert 'succeeded' condition explicitly.

How to verify it
Verified by cancelling and rerunning the azure pipeline.
