Does this PR require a change in the driver versions?

What this PR does / why we need it:

This PR enables kernel-testing framework on PRs.
I discovered that, for self hosted runners, there is no parallelism: each job's request is enqueued.
The only parallelism would happen if we had multiple self hosted runners under same tags, then the jobs would be distributed among them.

Same as create-comment.yml for perf but with diffeernt workflow_run trigger.

[FedeDP]

This is a fix :)

[FedeDP]

Once kernel-tests-dev finish, a new job will take care of uploading PR comment and info to be used by the matching create-comment.
Note: reusable_workflows do not support running as step, only job-wide ;)

[FedeDP]

Magic to get the first line that does not start with |, and head until it, so that we only print matrixes and not errors (full matrixes are still available as artifacts though).
