feat: install system extensions
Fixes #4815

This implements the following steps:

* machine configuration updates
* pulling and unpacking system extension images
* validating, listing system extensions
* re-packing system extensions
* preserving installed extensions in `/etc/extensions.yaml`

Once extension is enabled, raw information can be queried with:

```
$ talosctl -n 172.20.0.2 cat /etc/extensions.yaml
layers:
    - image: 000.ghcr.io-smira-gvisor-c927b54-dirty.sqsh
      metadata:
        name: gvisor
        version: 20220117.0-v1.0.0
        author: Andrew Rynhard
        description: |
            This system extension provides gVisor using containerd's runtime handler.
        compatibility:
            talos:
                version: '> v0.15.0-alpha.1'
```

This was tested with the `gvisor` system extension.
