Before the workspace changes, it was possible to include proto files via the
vendor path and the symlinks there. Now those symlinks are gone, so the search
path for them must be given separately.
Prior to this it would download Go, setup the environment, then (maybe)
download Go again.
I renamed verify_go_version to be internal and fixed all callers.
This helps 2 things:
1) output is cleaner
2) whether a build is static or non-static depends on string matching,
which is easier after this
If you specify a `...` pattern, this will preserve it, which breaks the
static/non-static matching but really, can we just agree that `make` is
for binaries? It works for other things but so does `go build`.
Example:
```
$ make WHAT="cmd/kubectl/ ./staging/src/k8s.io/api/... ./test/e2e/e2e.test ./test/e2e/e2e.test ./cmd/kubectl/ "
go version go1.21.4 linux/amd64

all callers of the "old" form will be fixed, and the "new" will be

- treat GOTOOLCHAIN set and !=auto like FORCE_HOST_GO
- otherwise set GOTOOLCHAIN=go${GO_VERSION} and fallback to gimme if necessary

Several verify scripts used the same pattern of "check for clean working tree,
generated files, check for diffs". The code for that is now in
kube::verify::generated, defined in hack/lib/verify-generated.sh, and those
scripts just source that.
