This involves moving the report files, but it allows me to delete the
indirect variable and indirect array code in update-codgen. As proud as
I was of figuring that out, I am also ashamed of myself for doing it.
This is my atonement.
The alternative to this would be to special-case code-generator. Since
it legit wants codegen, it seems wrong to make it be _examples (which tools
should ignore).
Make examples an "internal module" so the main go.mod for
k8s.io/code-generator does not get too polluted.
