Update Kunit (el9.4)

Update Kunit to include new tests and fixes. Tests that are running (but failing in ark) have been excluded.

Kunit is also now defaulting to disabled-- this should help reduce the very small overhead, and reduces attack surface on production.

Reviewers Note:

kunit tools patches are unused in our environment; however, due to the increase in changes that touch both kunit core and kunit tool files, these commits are included to avoid conflicts and diverging from upstream.
