Add verbosity to `controller-gen`

Recently I stumble upon a situation when running controller gen had no effect
```
controller-gen crd:headerFile="hack/boilerplate.go.txt",year=2024 paths="./pkg/api/..." output:dir="."

```

for the `crd` gen, but worked fine for `object` gen
```
controller-gen object:headerFile="hack/boilerplate.go.txt",year=2024 paths="./pkg/api/..."
```
(it produced output)

When I wanted to dig into it, I realized there is no way to enable `verbose` output in controller-gen, which would help to debug it.

Would be nice to have this feature
