This is going to be used to detect disks that are safe to wipe.
For blockdevices, track secondaries as direct references, e.g. encrypted
`STATE` partition might have secondary `vda5`.
For disks, re-map secondaries to be whole devices names, e.g. `vda`.

Uses go-siderolabs/go-blockdevice/v2 for all the hard parts,
provides new resource `Disk` which describes all disks in the system.
Additional resource `SystemDisk` always point to the system disk (based
on the location of `META` partition).
The `Disks` API (and `talosctl disks`) provides a view now into the
`talosctl get disks` to keep backwards compatibility.
QEMU provisioner can now create extra disks of various types: IDE, AHCI,
SCSI, NVME, this allows to test detection properly.
The new resource will be the foundation for volume provisioning (to pick
up the disk to provision the volume on).
Example:
```
talosctl -n 172.20.0.5 get disks
NODE NAMESPACE TYPE ID VERSION SIZE READ ONLY TRANSPORT ROTATIONAL WWID MODEL SERIAL
172.20.0.5 runtime Disk loop0 1 65568768 true

- By default, github.com/miekg/dns uses `dns.MinMsgSize` for UDP messages, which is 512 bytes. This is too small for some
DNS request/responses, and can cause truncation and errors. This change sets the buffer size to `dns.DefaultMsgSize`
4096 bytes, which is the maximum size of a dns packet payload per RFC 6891.
- We also retry the request if the response is truncated or previous connection was closed.
- And finally we properly handle the case where the response is larger than the client buffer size,
and we return a truncated correct response.

Note: this issue never happens with default Talos worker configuration
(generated by Omni, `talosctl gen config` or CABPT).
Before change https://github.com/siderolabs/talos/pull/4294 3 years ago,
worker nodes connected to trustd in "insecure" mode (without validating
the trustd server certificate). The change kept backwards compatibility,
so it still allowed insecure mode on upgrades.
Now it's time to break this compatibility promise, and require
accepted CAs to be always present. Adds validation for machine
configuration, so if upgrade is attempeted, it would not validate the
machine config without accepted CAs.
Now lack of accepted CAs would lead to failure to connect to trustd.
