This way the default gets populated on first start, when no existing
state exists to migrate. Also fix `ipn.PrefsFromBytes` to preserve empty
fields, rather than layering `NewPrefs` values on top.

Setting the field after-the-fact wasn't working because we could migrate
prefs on creation, which would set health status for auto updates.

In prep for making health warnings rich objects with metadata rather
than a bunch of strings, start moving it all into the same place.
We'll still ultimately need the stringified form for the CLI and
LocalAPI for compatibility but we'll next convert all these warnings
into Warnables that have severity levels and such, and legacy
stringification will just be something each Warnable thing can do.

Previously, policies affected the default prefs for a new profile, but
that does not affect existing profiles. This change ensures that
policies are applied whenever preferences are loaded or changed, so a
CLI or GUI client that does not respect the policies will still be
overridden.
Exit node IP is dropped from this PR as it was implemented elsewhere
in #10172.

This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled
clients can use this value to disambiguate fast user switching from one tailnet
to another that are under the same exact login. We will also try to backfill
this information during backend starts and profile switches so that users don't
have to re-authenticate their profile. The first client to use this new
information is the CLI in 'tailscale switch -list' which now uses text/tabwriter
to display the ID, Tailnet, and Account. Since account names are ambiguous, we
allow the user to pass 'tailscale switch ID' to specify the exact tailnet they
want to switch to.

We already removed the async API, make it more sync and remove
the FinishLogout state too.
This also makes the callback be synchronous again as the previous

in a client shutdown getting blocked forever.

Rather than make each ipn.StateStore implementation guard against
useless writes (a write of the same value that's already in the
store), do writes via a new wrapper that has a fast path for the
unchanged case.
This then fixes profileManager's flood of useless writes to AWS SSM,
etc.

This fix does not seem ideal, but the test infrastructure using a local
goos doesn't seem to avoid all of the associated challenges, but is
somewhat deeply tied to the setup.
The core issue this addresses for now is that when run on Windows there
can be no code paths that attempt to use an invalid UID string, which on
Windows is described in [1].
For the goos="linux" tests, we now explicitly skip the affected
migration code if runtime.GOOS=="windows", and for the Windows test we
explicitly use the running users uid, rather than just the string
"user1". We also now make the case where a profile exists and has
already been migrated a non-error condition toward the outer API.

I realized that a lot of the problems that we're seeing around migration and
LocalBackend state can be avoided if we drive Windows pref migration entirely
from within tailscaled. By doing it this way, tailscaled can automatically
perform the migration as soon as the connection with the client frontend is
established.
Since tailscaled is already running as LocalSystem, it already has access to
the user's local AppData directory. The profile manager already knows which
user is connected, so we simply need to resolve the user's prefs file and read
it from there.
Of course, to properly migrate this information we need to also check system
policies. I moved a bunch of policy resolution code out of the GUI and into
a new package in util/winutil/policy.

The profileManager was using the LoginName as a proxy to figure out if the profile
had logged in, however the LoginName is not present if the node was created with an
Auth Key that does not have an associated user.

The iOS has a command to reset the persisted state of the app, but it
was doing its own direct keychain manipulation. This proved to be
brittle (since we changed how preferences are stored with #6022), so
we instead add a LocalAPI endpoint to do do this, which can be updated
in tandem.
This clears the same state as the iOS implementation (tailscale/corp#3186),
that is the machine key and preferences (which includes the node key).
Notably this does not clear the logtail ID, so that logs from the device
still end up in the same place.

We would end up with duplicate profiles for the node as the UserID
would have chnaged. In order to correctly deduplicate profiles, we
need to look at both the UserID and the NodeID. A single machine can
only ever have 1 profile per NodeID and 1 profile per UserID.
Note: UserID of a Node can change when the node is tagged/untagged,
and the NodeID of a device can change when the node is deleted so we
need to check for both.

This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct.
This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey.
It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional
to be able to delete the "/tka" dir if it exists.
This means that we will have a unique key per profile, and a unique directory per profile.
Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not
delete the ChonkDir.
