This creates go.work and enables Go Workspaces. This is a file that
includes info on k/k and all the staging modules.
This depends on go 1.22 and setting FORCE_HOST_GO=true (for kube
scripts, which try to be hermetic).
Make this part of the normal update/verify sequence.
The top-level go.work file contains no replace statements. Instead, the
replace statements in the individual go.mod files are used. For this to
work, replace statements in the individual go.mod files have to be
consistent.
hack/tools has different dependencies and can't be in the main
workspace, so this adds a go.work just for that. Without this, go tries
to consider all deps in all modules and pick one that works for all.
This is problematic because there are so many of them that it is
difficult to manage.
Likewise for k8s.io/code-generator/examples and
k8s.io/kms/internal/plugins/_mock - add trivial go.work files.
For example k/k depends on an older version of a lib that gloangci-lint
needs (transitively) and it breaks.
This also updates vendor (needed to make go happy), and removes
vendor'ed symlinks. This breaks a LOT of our build tools, which will be
fixed subsequently.
Result: `go` commands work across modules:
Before:
```
$ go list ./pkg/proxy/iptables/ ./staging/src/k8s.io/api/core/v1/
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api/core/v1
$ go build ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api
$ go test ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api
```
After:
```
$ go list ./pkg/proxy/iptables/ ./staging/src/k8s.io/api/core/v1/
k8s.io/kubernetes/pkg/proxy/iptables
k8s.io/api/core/v1
$ go build ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
$ go test ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
ok k8s.io/kubernetes/pkg/proxy/iptables 0.360s
ok k8s.io/api 2.302s
```
Result: `make` fails:
```

Again, this requires go 1.22 (e.g. gotip), as go 1.21.x does not have
`go work vendor` support.

The pull-kubernetes-verify job is using this to run the base
verify-golangci.sh only in the pull-kubernetes-verify-lint job.
Because the file name was not quite right, it still ran.
Wrapping errors may or may not be the right thing to do (see
https://go.dev/blog/go1.13-errors#whether-to-wrap and the discussion in
https://github.com/kubernetes/kubernetes/issues/123234). But developers should
at least think about it, so let's emit linter hints for it: the golangci-lint
config by default enables it for go-errorlint, just not the linter itself, so
we just need to add it for the "hints" config.
Direct error comparisons and assertions also get checked. Those are typically
something that should be replaced by errors.Is and errors.As, but as the
existing code often doesn't do that, let's also treat those as just hints.
Fixed the following Pylint warnings:
boilerplate_test.py:34:8: R0205: Class 'Args' inherits from object, can be safely removed from bases in python3 (useless-object-inheritance)

GNU xargs has a `-r, --no-run-if-empty` option but I don't think we want
to depend on GNU (thanks, MacOS).
Why? Sometimes, when you are messing with codegens, you end up with an
empty input and then it just hangs.
