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.

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.

We already have the code which supports custom enums, so let's extend it to support custom enums in slices and
fix the NfTablesConntrackStateMatch proto definition.

Many changes to the nftables backend which will be used in the follow-up
PR with #4421.
1. Add support for chain policy: drop/accept.
2. Properly handle match on all IPs in the set (`0.0.0.0/0` like).
3. Implement conntrack state matching.
4. Implement multiple ifname matching in a single rule.
5. Implement anonymous counters.

Network probes are configured with the specs, and provide their output
as a status.
At the moment only platform code can configure network probes.
If any network probes are configured, they affect network.Status
'Connectivity' flag.
Example, create the probe:
```
talosctl -n 172.20.0.3 meta write 0xa '{"probes": [{"interval": "1s", "tcp": {"endpoint": "google.com:80", "timeout": "10s"}}]}'
```
Watch probe status:
```
$ talosctl -n 172.20.0.3 get probe
NODE NAMESPACE TYPE ID VERSION SUCCESS
172.20.0.3 network ProbeStatus tcp:google.com:80 5 true
```
With failing probes:
```
$ talosctl -n 172.20.0.3 get probe
NODE NAMESPACE TYPE ID VERSION SUCCESS
172.20.0.3 network ProbeStatus tcp:google.com:80 4 true
172.20.0.3 network ProbeStatus tcp:google.com:81 1 false
$ talosctl -n 172.20.0.3 get networkstatus
NODE NAMESPACE TYPE ID VERSION ADDRESS CONNECTIVITY HOSTNAME ETC
172.20.0.3 network NetworkStatus status 5 true true true true
```

This adds support for automatically registering node hostnames in DNS by
sending the current hostname to DHCP via option 12. If the current hostname is
updated, issue a new DISCOVER to propagate the update to DHCP (updating the
hostname on lease renewals is not universally supported by DHCP servers). This
addition maintains the previous functionality where the node can also request
its hostname from the DHCP server. The received hostname will be processed and
prioritized as usual by the `network.HostnameSpecController`.
This change set also contains fixes to make DHCP renewals compliant with RFC
2131, specifically avoiding sending the server identifier and requested IP
address when issuing renewals using a previous offer. This also uncovered
issues and missing features in the upstream `insomniacslk/dhcp` library, the
fixes and improvements for which are now finally merged.
Sending hostname updates have been tested against `dnsmasq` and the built-in
DHCP + DNS services in Windows Server. Hostname retrieval from DHCP and edge
cases with overridden hostnames from different configuration layers have been
extensively tested against `dnsmasq`.

Introduce new DHCP operator option to skip hostname request/response,
and use that in OpenStack platform.
OpenStack configures interface with DHCP, while providing dummy hostname
over DHCP and proper hostname over metadata. As operators override
platform settings, DHCP hostname takes over OpenStack hostname. As a
fix, ignore DHCP hostname while on OpenStack.
Fixes#6350

Permanent address is only available for physical links, and it might be
different from the 'hardware address': when bonding, 'hardware address'
gets overridden from the bond master, while 'permanent address' still
shows MAC of the interface.
This part of the fix for incorrect bonding issue on Equinix Metal.
