This is step 4 of making syspolicy a build-time feature.
This adds a policyclient.Get() accessor to return the correct
implementation to use: either the real one, or the no-op one. (A third
type, a static one for testing, also exists, so in general a
policyclient.Client should be plumbed around and not always fetched
via policyclient.Get whenever possible, especially if tests need to use
alternate syspolicy)

Step 4 of N. See earlier commits in the series (via the issue) for the
plan.
This adds the missing methods to policyclient.Client and then uses it
everywhere in ipn/ipnlocal and locks it in with a new dep test.
Still plenty of users of the global syspolicy elsewhere in the tree,
but this is a lot of them.

Step 3 in the series. See earlier cc532efc20 and d05e6dc09e.
This step moves some types into a new leaf "ptype" package out of the
big "settings" package. The policyclient.Client will later get new
methods to return those things (as well as Duration and Uint64, which
weren't done at the time of the earlier prototype).

This is step 1 of ~3, breaking up #14720 into reviewable chunks, with
the aim to make syspolicy be a build-time configurable feature.
In this first (very noisy) step, all the syspolicy string key
constants move to a new constant-only (code-free) package. This will
make future steps more reviewable, without this movement noise.
There are no code or behavior changes here.
The future steps of this series can be seen in #14720: removing global
funcs from syspolicy resolution and using an interface that's plumbed
around instead. Then adding build tags.

If you had HTTPS_PROXY=https://some-valid-cert.example.com running a
CONNECT proxy, we should've been able to do a TLS CONNECT request to
e.g. controlplane.tailscale.com:443 through that, and I'm pretty sure
it used to work, but refactorings and lack of integration tests made
it regress.
It probably regressed when we added the baked-in LetsEncrypt root cert
validation fallback code, which was testing against the wrong hostname
(the ultimate one, not the one which we were being asked to validate)

Previously all tests shared their tailscale+tailscaled binaries in
system /tmp directories, which often leaked, and required TestMain to
clean up (which feature/taildrop didn't use).
This makes it use testing.T.TempDir for the binaries, but still only
builds them once and efficiently as possible depending on the OS
copies them around between each test's temp dir.

ResourceCheck was previously using cmp.Diff on multiline goroutine stacks
The produced output was difficult to read for a number of reasons:
- the goroutines were sorted by count, and a changing count caused them to
jump around
- diffs would be in the middle of stacks
Instead, we now parse the pprof/goroutines?debug=1 format goroutines and
only diff whole stacks.

This adds netx.DialFunc, unifying a type we have a bazillion other
places, giving it now a nice short name that's clickable in
editors, etc.
That highlighted that my earlier move (03b47a55c7) of stuff from
nettest into netx moved too much: it also dragged along the memnet
impl, meaning all users of netx.DialFunc who just wanted netx for the
type definition were instead also pulling in all of memnet.
So move the memnet implementation netx.Network into memnet, a package
we already had.
Then use netx.DialFunc in a bunch of places. I'm sure I missed some.
And plenty remain in other repos, to be updated later.

So split out the non-test stuff of nettest into its own package.
We tend to use "foox" as the convention for things we wish were in the
standard library's foo package, so "netx" seems consistent.

In this PR, we update ipnlocal.LocalBackend to allow registering callbacks for control client creation
and profile changes. We also allow to register ipnauth.AuditLogFunc to be called when an auditable
action is attempted.
We then use all this to invert the dependency between the auditlog and ipnlocal packages and make
the auditlog functionality optional, where it only registers its callbacks via ipnlocal-provided hooks
when the auditlog package is imported.
We then underscore-import it when building tailscaled for Windows, and we'll explicitly
import it when building xcode/ipn-go-bridge for macOS. Since there's no default log-store
location for macOS, we'll also need to call auditlog.SetStoreFilePath to specify where
pending audit logs should be persisted.

If we get a packet in over some DERP and don't otherwise know how to
reply (no known DERP home or UDP endpoint), this makes us use the
DERP connection on which we received the packet to reply. This will
almost always be our own home DERP region.
This is particularly useful for large one-way nodes (such as
hello.ts.net) that don't actively reach out to other nodes, so don't
need to be told the DERP home of peers. They can instead learn the
DERP home upon getting the first connection.
This can also help nodes from a slow or misbehaving control plane.

In this PR, we enable the registration of LocalBackend extensions to exclude code specific to certain
platforms or environments. We then introduce desktopSessionsExt, which is included only in Windows builds
and only if the ts_omit_desktop_sessions tag is disabled for the build. This extension tracks desktop sessions
and switches to (or remains on) the appropriate profile when a user signs in or out, locks their screen,
or disconnects a remote session.
As desktopSessionsExt requires an ipn/desktop.SessionManager, we register it with tsd.System
for the tailscaled subprocess on Windows.
We also fix a bug in the sessionWatcher implementation where it attempts to close a nil channel on stop.

In v1.78, we started acquiring the GP lock when reading policy settings. This led to a deadlock during
Tailscale installation via Group Policy Software Installation because the GP engine holds the write lock
for the duration of policy processing, which in turn waits for the installation to complete, which in turn
waits for the service to enter the running state.
In this PR, we prevent the acquisition of GP locks (aka EnterCriticalPolicySection) during service startup
and update the Windows Registry-based util/syspolicy/source.PlatformPolicyStore to handle this failure
gracefully. The GP lock is somewhat optional; it’s safe to read policy settings without it, but acquiring
the lock is recommended when reading multiple values to prevent the Group Policy engine from modifying
settings mid-read and to avoid inconsistent results.

This pulls out the Wake-on-LAN (WoL) code out into its own package
(feature/wakeonlan) that registers itself with various new hooks
around tailscaled.
Then a new build tag (ts_omit_wakeonlan) causes the package to not

Ohter new packages include:
* feature: to just record which features are loaded. Future:
dependencies between features.
* feature/condregister: the package with all the build tags
that tailscaled, tsnet, and the Tailscale Xcode project
extension can empty (underscore) import to load features
as a function of the defined build tags.
Future commits will move of our "ts_omit_foo" build tags into this

Otherwise all the clients only using control/controlhttp for the
ts2021 HTTP client were also pulling in WebSocket libraries, as the
server side always needs to speak websockets, but only GOOS=js clients
speak it.
This doesn't yet totally remove the websocket dependency on Linux because
Linux has a envknob opt-in to act like GOOS=js for manual testing and force
the use of WebSockets for DERP only (not control). We can put that behind
a build tag in a future change to eliminate the dep on all GOOSes.
