I'm on a mission to simplify LocalBackend.Start and its locking
and deflake some tests.
I noticed this hasn't been used since March 2023 when it was removed
from the Windows client in corp 66be796d33c.
So, delete.

This is primarily for GUIs, so they don't need to remember the most
recently used exit node themselves.
This adds some CLI commands, but they're disabled and behind the WIP
envknob, as we need to consider naming (on/off is ambiguous with
running an exit node, etc) as well as automatic exit node selection in
the future. For now the CLI commands are effectively developer debug
things to test the LocalAPI.

This names the func() that Once-unlocked LocalBackend.mu. It does so
both for docs and because it can then have a method: Unlock, for the
few points that need to explicitly unlock early (the cause of all this
mess). This makes those ugly points easy to find, and also can then
make them stricter, panicking if the mutex is already unlocked. So a
normal call to the func just once-releases the mutex, returning false
if it's already done, but the Unlock method is the strict one.
Then this uses it more, so most the b.mu.Unlock calls remaining are
simple cases and usually defers.

A number of methods in LocalBackend (with suffixed "LockedOnEntry")
require b.mu be held but unlock it on the way out. That's asymmetric
and atypical and error prone.
This adds a helper method to LocalBackend that locks the mutex and
returns a sync.OnceFunc that unlocks the mutex. Then we pass around
that unlocker func down the chain to make it explicit (and somewhat
type check the passing of ownership) but also let the caller defer
unlock it, in the case of errors/panics that happen before the callee
gets around to calling the unlock.
This revealed a latent bug in LocalBackend.DeleteProfile which double
unlocked the mutex.

First we had Capabilities []string. Then
https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a
superset of Capabilities. Except we never really finished the
transition inside the codebase to go all-in on CapMap. This does so.
Notably, this coverts Capabilities on the wire early to CapMap
internally so the code can only deal in CapMap, even against an old
control server.
In the process, this removes PeerChange.Capabilities support, which no
known control plane sent anyway. They can and should use
PeerChange.CapMap instead.

If the client uses the default Tailscale control URL, validate that all
PopBrowserURLs are under tailscale.com or *.tailscale.com. This reduces
the risk of a compromised control plane opening phishing pages for
example.
The client trusts control for many other things, but this is one easy
way to reduce that trust a bit.

This is a temporary solution to at least omit Mullvad exit nodes
from the list of TailFS peers. Once we can identify peers that are
actually sharing via TailFS, we can remove this, but for alpha it'll
be sufficient to just omit Mullvad.

Moving logic that manipulates a ServeConfig into recievers on the
ServeConfig in the ipn package. This is setup work to allow the
web client and cli to both utilize these shared functions to edit
the serve config.
Any logic specific to flag parsing or validation is left untouched
in the cli command. The web client will similarly manage its
validation of user's requested changes. If validation logic becomes
similar-enough, we can make a serve util for shared functionality,
which likely does not make sense in ipn.

This fixes a regression introduced with 993acf4 and released in
v1.60.0.
The regression caused us to intercept all userspace traffic to port
8080 which prevented users from exposing their own services to their
tailnet at port 8080.
Now, we only intercept traffic to port 8080 if it's bound for
100.100.100.100 or fd7a:115c:a1e0::53.

This adds a method to wgengine.Engine and plumbed down into magicsock
to add a way to get a type-safe Tailscale-safe wrapper around a
wireguard-go device.Peer that only exposes methods that are safe for
Tailscale to use internally.
It also removes HandshakeAttempts from PeerStatusLite that was just
added as it wasn't needed yet and is now accessible ala cart as needed
from the Peer type accessor.
None of this is used yet.
