In preparation for multi-user and unattended mode improvements, we are
refactoring and cleaning up `ipn/ipnlocal.profileManager`. The concept of the
"current user", which is only relevant on Windows, is being deprecated and will
soon be removed to allow more than one Windows user to connect and utilize
`LocalBackend` according to that user's access rights to the device and specific
Tailscale profiles.
We plan to pass the user's identity down to the `profileManager`, where it can
be used to determine the user's access rights to a given `LoginProfile`. While
the new permission model in `ipnauth` requires more work and is currently
blocked pending PR reviews, we are updating the `profileManager` to reduce its
reliance on the concept of a single OS user being connected to the backend at
the same time.
We extract the switching to the default Tailscale profile, which may also
trigger legacy profile migration, from `profileManager.SetCurrentUserID`. This
introduces `profileManager.DefaultUserProfileID`, which returns the default
profile ID for the current user, and `profileManager.SwitchToDefaultProfile`,
which is essentially a shorthand for `pm.SwitchProfile(pm.DefaultUserProfileID())`.
Both methods will eventually be updated to accept the user's identity and
utilize that user's default profile.
We make access checks more explicit by introducing the `profileManager.checkProfileAccess`
method. The current implementation continues to use `profileManager.currentUserID`
and `LoginProfile.LocalUserID` to determine whether access to a given profile
should be granted. This will be updated to utilize the `ipnauth` package and the
new permissions model once it's ready. We also expand access checks to be used
more widely in the `profileManager`, not just when switching or listing
profiles. This includes access checks in methods like `SetPrefs` and, most notably,
`DeleteProfile` and `DeleteAllProfiles`, preventing unprivileged Windows users
from deleting Tailscale profiles owned by other users on the same device,
including profiles owned by local admins.
We extract `profileManager.ProfilePrefs` and `profileManager.SetProfilePrefs`
methods that can be used to get and set preferences of a given `LoginProfile` if
`profileManager.checkProfileAccess` permits access to it.
We also update `profileManager.setUnattendedModeAsConfigured` to always enable
unattended mode on Windows if `Prefs.ForceDaemon` is true in the current
`LoginProfile`, even if `profileManager.currentUserID` is `""`. This facilitates
enabling unattended mode via `tailscale up --unattended` even if
`tailscale-ipn.exe` is not running, such as when a Group Policy or MDM-deployed
script runs at boot time, or when Tailscale is used on a Server Code or otherwise
headless Windows environments. See #12239, #2137, #3186 and
https://github.com/tailscale/tailscale/pull/6255#issuecomment-2016623838 for

This improves convenience and security.
* Convenience - no need to see nodes that can't share anything with you.
* Security - malicious nodes can't expose shares to peers that aren't
allowed to access their shares.
