Fixes#4816
This changes the way system extensions are packaged into the squashfs
images: `/lib/firmware` is now moved out of the future squashfs images
and becomes part of `initramfs` to make firmware available in the early
boot.
Talos will bind-mount `/lib/firmware` into rootfs as well, so it will be
available in the rootfs as well.

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
