Otsca test

[siemen11]

Add scripts on how to chain commands for each test of the current testOS, add a Bazel framework which extends the opentitan repo's, add test scripts to test the testOS from the host scripts.

[siemen11]

This can have lower priority to be merged.

What still needs to be done:

• to see whether these scripts are compatible with FPGA testing (I don't have an FPGA available at the moment)
• to make the tests and host scripts better via templates (meaning there is a lot of similarity between large parts of the code)
• a nice to have is to further extend the bazel and test framework to include the other scripts in testing

Feel free to add more to-do's to improve this

FPGA part is done now

Thanks Siemen for working this, having a test framework for ot-sca <-> pentest framework does have a huge impact on the maintainability of the pentesting infrastructure :)

I've dropped a couple of comments. It seems that your changes broke the current SCA capture scripts (please see the CI). In order to merge this we would need to make sure that they still work.

Sadly I must admin defeat in that I couldn't get OpenTitan's lint targets work for this WORKSPACE so licenses and empty lines added manually for now

Thanks Siemen. I'd suggest a couple of points before we can merge this:

• Can you please rebase the PR such that we see that CI passes?
• Would it be possible to add a very brief documentation to test/penetrationtests, i.e., a brief how to run this?
• Could you please squash some of the commits? E.g., creating a new communication folder and then moving it again at the end?
• Would it be possible to move the default configs for the target/communication scripts outside of these functions?
