There's a cyclic dependency on siderolink library which imports talos
machinery back. We will fix that after we get talos pushed under a new
name.

This the first step towards replacing all import paths to be based on
`siderolabs/` instead of `talos-systems/`.
All updates contain no functional changes, just refactorings to adapt to
the new path structure.

There should be no functional change with this PR.
The primary driver is supporting strategic merge configuration patches.
For such type of patches machine config should be loaded from incomplete
fragments, so it becomes critically important to distinguish between a
field having zero value vs. field being set in YAML.
E.g. with following struct:
```go
struct { AEnabled *bool `yaml:"a"` }
```
It's possible to distinguish between:
```yaml
a: false
```
and no metion of `a` in YAML.
Merging process trewats zero values as "not set" (skips them when
merging), so it's important to allow overriding value to explicit
`false`.

This is next part of networkd rewrite.
This implements three new resource types coupled with controllers which
process the default configuration, merges and applying changes.
TimeSync was set up to watch the time servers resource. This is a no-op
for now, but once DHCP is implemented, this would enable time server
configuration coming from DHCP.

The structure of the controllers is really similar to addresses and
routes:
* `LinkSpec` resource describes desired link state
* `LinkConfig` controller generates `LinkSpecs` based on machine
configuration and kernel cmdline
* `LinkMerge` controller merges multiple configuration sources into a
single `LinkSpec` paying attention to the config layer priority
* `LinkSpec` controller applies the specs to the kernel state
Controller `LinkStatus` (which was implemented before) watches the
kernel state and publishes current link status.

Enable logging using default development config with some fine tuning.
Additionally, now `info` and below logs go to kmsg.

This is a complete rewrite of time sync process.
Now the time sync process starts early at boot time, and it adapts to
configuration changes:
* before config is available, `pool.ntp.org` is used
* once config is available, configured time servers are used
Controller updates same time sync resource as other controllers had
dependency on, so they have a chance to wait for the time sync event.
Talos services which depend on time now wait on same resource instead of
waiting on timed health.
New features:
* time sync now sticks to the particular time server unless there's an
error from that server, and server is changed in that case, this
improves time sync accuracy
* time sync acts on config changes immediately, so it's possible to
reconfigure time sync at any time
* there's a new 'epoch' field in time sync resources which allows
time-dependent controllers to regenerate certs when there's a big enough
jump in time
Features to implement later:
* apid shouldn't depend on timed, it should be started early and it
should regenerate certs on time jump
* trustd should be updated in same way
