When we first made Tailscale SSH, we assumed people would want public
key support soon after. Turns out that hasn't been the case; people
love the Tailscale identity authentication and check mode.
In light of CVE-2024-45337, just remove all our public key code to not
distract people, and to make the code smaller. We can always get it
back from git if needed.
