Generate remaining CRDs based on vendored APIs (gardener#8560)

* Generate `druid.gardener.cloud` CRDs based on vendored `etcd-druid` version

* Generate HVPA `autoscaling.k8s.io` CRDs based on vendored `hvpa-controller` version

* Rename VPA CRD files

For better/easier Git diff in next commit

* Generate VPA `autoscaling.k8s.io` CRDs based on vendored `autoscaler` version

* Remove `/scale` subresource from `etcds.druid.gardener.cloud` CRD

/scale subresource is intentionally removed from this CRD, although it is specified in the original CRD from etcd-druid, due to adverse interaction with VPA.
See gardener#6850 and gardener#8560 (comment)

* Vendor `github.com/gardener/etcd-druid@v1.20.1`

follow-up of gardener#8605
