Step 1 of many, cleaning up the direct/auto client & restarting map
requests that leads to all the unnecessary map requests.

We can't do Noise-over-HTTP in Wasm/JS (because we don't have bidirectional
communication), but we should be able to do it over WebSockets. Reuses
derp WebSocket support that allows us to turn a WebSocket connection
into a net.Conn.

Currently, when SetNetInfo is called it sets the value on
hostinfo.NetInfo. However, when SetHostInfo is called it overwrites the
hostinfo field which may mean it also clears out the NetInfo it had just
received.
This commit stores NetInfo separately and combines it into Hostinfo as
needed so that control is always notified of the latest values.
Also, remove unused copies of Hostinfo from ipn.Status and
controlclient.Auto.

The connections returned from SystemDial are automatically closed when
there is a major link change.
Also plumb through the dialer to the noise client so that connections
are auto-reset when moving from cellular to WiFi etc.

In debugging #4541, I noticed this log print was always empty.
The value printed was always zero at this point.

For people running self-hosted control planes who want a global
opt-out knob instead of running their own logcatcher.

tailcfg.PingResponse formalizes the TSMP & disco response message, and
controlclient is wired to send POST responses containing
tailcfg.PingResponse for TSMP and disco PingRequests.

And add a CapabilityVersion type, primarily for documentation.
This makes MapRequest.Version, RegisterRequest.Version, and
SetDNSRequest.Version all use the same version, which will avoid
confusing in the future if Register or SetDNS ever changed their
semantics on Version change. (Currently they're both always 1)
This will requre a control server change to allow a
SetDNSRequest.Version value other than 1 to be deployed first.

Otherwise omitempty doesn't work.
This is wire-compatible with a non-pointer type, so switching
is safe, now and in the future.

The TODO is done. Magicsock doesn't require any endpoints to create an
*endpoint now. Verified both in code and empirically: I can use the
env knob and access everything.

A new package can also later record/report which knobs are checked and
set. It also makes the code cleaner & easier to grep for env knobs.

* types/key: add ControlPrivate, with custom serialization.
ControlPrivate is just a MachinePrivate that serializes differently
in JSON, to be compatible with how the Tailscale control plane
historically serialized its private key.
