4001d0bf25 assorted: plumb tka initialization & network-lock key into tailscaled
- A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration.
 - If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

    perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. )
    goimports -w .

Then delete some stuff from the net/netaddr shim package which is no
longer neeed.

Finally, removed the net/netaddr wrappers, to prevent future use.

tailcfg: add TailscaleSSHEnabled helper check (#4812)
This commit adds a helper to check if Tailscale SSH is enabled. We're
currently checking the SSH_HostKeys field in a few places, but later
plan to add an explicit bool. This helper makes the check and any future
changes easier.

24cd26534f hostinfo, tailcfg: add desktop detection on Linux to hostinfo
From the machines tab its hard to differenciate desktop Linux installs from
server Linux installs. Transmitting this information should make this
determination a lot easier.

Due to the reality that tailscaled is likely a system process, the standard
checks based on XDG_SESSION_TYPE or DISPLAY environment variables are not
possible (those variables won't be set). Instead, we look for listening
unix sockets that are typical of desktop installs.
