kubeadm: Remove the never-used .Etcd.SelfHosted field

**What this PR does / why we need it**:
These API types were added to support the self-hosting etcd feature, which in the end never was merged. Hence these API types are unused and should be removed. Perfect timing to do that is now in our new `v1alpha2` scheme.

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Part of https://github.com/kubernetes/community/pull/2131

**Special notes for your reviewer**:
Depends on PRs:
 - [x] #63799
 - [x] #63788

**Release note**:

```release-note
kubeadm has removed `.Etcd.SelfHosting` from its configuration API. It was never used in practice.
```
