Adds a new Mode to the web server, indicating the specific
scenario the constructed server is intended to be run in. Also
starts filling this from the cli/web and ipn/ipnlocal callers.
From cli/web this gets filled conditionally based on whether the
preview web client node cap is set. If not set, the existing
"legacy" client is served. If set, both a login/lobby and full
management client are started (in "login" and "manage" modes
respectively).

Now uses webClientAtomicBool as the source of truth for whether the web
client should be running in tailscaled, with it updated when either the
RunWebClient pref or CapabilityPreviewWebClient node capability changes.
This avoids requiring holding the LocalBackend lock on each call to
ShouldRunWebClient to check for the CapabilityPreviewWebClient value.
