This PR adds the support for CoreDNS forwarding to host DNS. We try to bind on 9th address on the first element from
`serviceSubnets` and create a simple service so k8s will not attempt to rebind it.

Turns out there is actually no black magic in systemd, they simply listen on 127.0.0.53 and forward dns requests there in resolv.conf.
Reason is the same as ours — to preserve compatibility with other applications. So we do the same in our code.
This PR also does two things:
- Adds `::1` into resolv.conf for IPv6 only resolvers.
- Drops `SO_REUSEPORT` from control options (it works without them).

This errors pops up when `udevd` rescans the partition table with Talos
trying to mount a device concurrently.
This feels to be something new with Linux 6.6 probably.

This PR adds a new controller - `DNSServerController` that starts tcp and udp dns servers locally. Just like `EtcFileController` it monitors `ResolverStatusType` and updates the list of destinations from there.
Most of the caching logic is in our "lobotomized" "`CoreDNS` fork. We need this fork because default `CoreDNS` carries
full Caddy server and various other modules that we don't need in Talos. On our side we implement
random selection of the actual dns and request forwarding.

When the dashboard is used via the CLI through a proxy, e.g., through Omni, node names or IDs can be used in the `--nodes` flag instead of the IPs.
This caused rendering inconsistencies in the dashboard, as some parts of it used the IPs and some used the names passed in the context.
Fix this by collecting all node IPs on dashboard start, and map these IPs to the respective nodes passed as the `--nodes` flag.
On the dashboard footer, we always display the node names as they are passed in the `--nodes` flag.
As part of it, remove the node list change reactivity from the dashboard, so it will always take the passed nodes as the truth.
The IP to node mapping collection at dashboard startup also solves another issue where the first API call by the dashboard triggered the interactive API authentication (e.g., the OIDC flow). Previously, because the terminal was already switched to the raw mode, it was not possible to authenticate properly.

This PR does those things:
- It allows API calls `MetaWrite` and `MetaRead` in maintenance mode.
- SystemInformation resource now waits for available META
- SystemInformation resource now overwrites UUID from META if there is an override
- META now supports "UUID override" and "unique token" keys
- ProvisionRequest now includes unique token and Talos version

First of all, this interface is way more performant than `pcap`
interface. It is Linux-specific, but we don't care in Talos Linux :)
Second, this drop dependency of `machined` on `gopacket/layers` package,
which has huge issues with memory allocations and startup time.
This cuts around 20MiB of process RSS for all Talos processes.
(`talosctl` still requires this `gopacket/layers` library for decoding
packets).

The conversion from TPM 2 hash algorithm to Go crypto algorithm will fail for
uncommon algorithms like SM3256. This can be avoided by checking the constants
directly, rather than converting them. It should also be fine to allow some non

Short version is: move from global variables/`init()` function into
explicit functions.
`docgen` was updated to skip creating any top-level global variables,
now `Doc` information is generated on the fly when it is accessed.
Talos itself doesn't marshal the configuration often, so in general it
should never be accessed for Talos (but will be accessed e.g. for
`talosctl`).
Machine config examples were changed manually from variables to
functions returning a value and moved to a separate file.
There are no changes to the output of `talosctl gen config`.
There is a small change to the generated documentation, which I believe
is a correct one, as previously due to value reuse it was clobbered with
other data.

Use `Progress`, and options to pass around the way messages are written.
Fixed some tiny issues in the code, but otherwise no functional changes.
To make colored output work with `docker run`, switched back image
generation to use volume mount for output (old mode is still
functioning, but it's not the default, and it works when docker is not
running on the same host).

There are two changes here:
* build `machined` binary with `tcell_minimal` tag (which disables
loading some parts of the terminfo database), which also affects
`apid`, `trustd` and `dashboard` processes, as they run from the same
executable; in `dashboard` explicitly import `linux` terminal we're
using when the `dashboard` runs on the machine
* pass `TCELL_MINIMIZE=1` environment variable to each Talos process
which removes 0.5MiB of runewdith allocation for a lookup table

Currently, we use `github.com/coreos/go-semver/semver` and `github.com/hashicorp/go-version`

has more features, it makes sense to use it across the projects. It also doesn't allocate
