feat: add KMS assisted encryption key handler
Talos now supports new type of encryption keys which rely on Sealing/Unsealing randomly generated bytes with a KMS server:

```
systemDiskEncryption:
  ephemeral:
    keys:
      - kms:
          endpoint: https://1.2.3.4:443
        slot: 0
```
gRPC API definitions and a simple reference implementation of the KMS server can be found in this
[repository](https://github.com/siderolabs/kms-client/blob/main/cmd/kms-server/main.go).
