smsc/accelerator: add new smsc component

[edgargabriel]

• add smsc component based on the accelerator API IPC functionality.
• adjust smsc base selection logic to enable a pass-through mechanism with the new smsc/accelerator component

@edgargabriel Could you explain how this change can be tested? We can run it through AWS CI.

[edgargabriel]

@wenduwan Assuming that you do not have AMD GPUs, I think the prerequisite for testing this PR would require the accelerator/cuda component to implement the missing IPC functionality.

[bosilca]

Give me a week or so to add support for CUDA.

btw. I have no clue why the continuous-integration/jenkins/pr-head is marked as 'failed'. If you click on Details, all tests seemed to have passed correctly

I find jenkins pipeline graph visually misleading. The pipeline steps page shows the failure

@wenduwan thank you, will need to check, probably forgot to add a file somewhere
