this allows us to maintain the bazel build files until they're removed,
but tries to avoid accidentally encouraging their use
`make update-all` implementes a non-bazel version of
`hack/update-all.sh`, with `hack/update-all.sh` now calling make but
also doing the bazel stuff it used to.

- runs "make update-codegen"
- adds codegen verification to make tests
- changes hack/(update|verify)-codegen.sh to just call make
- removes bazel codegen test so it's not automatically run in CI
