This runs much faster than before. This change removes all of the
async status output because all of the compute time is spent inside
go/packages, with no opportunity to update the status.
Adds testdata code to prove it fails when expected.
- add ./hack/tools/go.mod, this makes ./hack/tools a distinct module
- hack/tools/tools.go undescore imports bazel related tools, over time we
can add others.
- hack/*.sh scripts will cd to hack/tools and go install tools from there
