Update KUNIT for el9.3

This rebase brings in new kunit tests that we are already running for
ARK. Enable these here to increase our downstream testing efforts.
    
Specifically disable the CLK test. We have this enabled in ARK and have
been seeing unstable results since it has been added upstream, as well
as issues downstream here.

Reviewers Note:

My previous kunit rebases have avoided bringing in as many as the kunit tools patches as they are unused in our environment; however, due to the increase in changes that touch both kunit core and kunit tool files, these backports become more tedious. Because we dont utilize the kunit tools folder there is no harm in pulling in these patches.
