The StartLoginInteractive command is for delegating the sign-in flow
to a browser. The Android Gooogle Sign-In SDK inverts the flow by
giving the client ID tokens.
Add a new backend command for accepting such tokens by exposing the existing
controlclient.Client.Login support for OAuth2 tokens. Introduce a custom
TokenType to distinguish ID tokens from other OAuth2 tokens.

We want the macOS Network Extension to share fate with the UI frontend,
so we need the backend to know when the frontend disappears.
One easy way to do that is to reuse the existing TCP server it's
already running (for tailscale status clietns).
We now tell the frontend our ephemeral TCP port number, and then have
the UI connect to it, so the backend can know when it disappears.
There are likely Swift ways of doing this, but I couldn't find them
quickly enough, so I reached for the hammer I knew.
Use this when making the ipn state transition from Starting to
Running. This way a network of quiet nodes with no active
handshaking will still transition to Active.

Prefs has become a heavy object with non-memcpy copy
semantics. We should not pass such a thing by value.

We can't rely on a frontend to provide a control
server URL, so this naturally belongs in server-persisted
state.

The store is passed-in by callers of NewLocalBackend and
ipnserver.Run, but currently all callers are hardcoded to
an in-memory store. The store is unused.

This is a prelude to making it truly optional, once state
management has moved into the backend. For now though, it's
still required. This change is just isolating the bubbling-up
of the pointerification into other layers.

- It was only used in one currently-unused client.
- It's an imperative command, not a configuration setting.
- The LoginFlags stuff in controlclient feels like it needs
a refactor anyway.
I'll put this logic back once ipnd owns its state and Backend
commands reflect that.
