This PR adds a new field to the serve config that can be used to identify which serves are in "foreground mode" and then can also be used to ensure they do not get persisted to disk so that if Tailscaled gets ungracefully shutdown, the reloaded ServeConfig will not have those ports opened.

In preparing for incoming CLI changes, this PR merges the code path for the `serve` and `funnel` subcommands.
See the parent issue for more context.
The following commands will run in foreground mode when using the environment flag.
```
tailscale serve localhost:3000
tailscae funnel localhost:3000
```

This option allows logging the raw HTTP requests and responses that the
portmapper Client makes when using UPnP. This can be extremely helpful
when debugging strange UPnP issues with users' devices, and might allow
us to avoid having to instruct users to perform a packet capture.

* We update wingoes to pick up new version information functionality
(See pe/version.go in the https://github.com/dblohm7/wingoes repo);
* We move the existing LogSupportInfo code (including necessary syscall
stubs) out of util/winutil into a new package, util/osdiag, and implement
the public LogSupportInfo function may be implemented for other platforms
as needed;
* We add a new reason argument to LogSupportInfo and wire that into
localapi's bugreport implementation;
* We add module information to the Windows implementation of LogSupportInfo
when reason indicates a bugreport. We enumerate all loaded modules in our
process, and for each one we gather debug, authenticode signature, and
version information.

While our `shouldStartDomainRenewal` check is correct, `getCertPEM`
would always bail if the existing cert is not expired. Add the same
`shouldStartDomainRenewal` check to `getCertPEM` to make it proceed with
renewal when existing certs are still valid but should be renewed.
The extra check is expensive (ARI request towards LetsEncrypt), so cache
the last check result for 1hr to not degrade `tailscale serve`
performance.
Also, asynchronous renewal is great for `tailscale serve` but confusing
for `tailscale cert`. Add an explicit flag to `GetCertPEM` to force a
synchronous renewal for `tailscale cert`.

Define PeerCapabilty and PeerCapMap as the new way of sending down
inter-peer capability information.
Previously, this was unstructured and you could only send down strings
which got too limiting for certain usecases. Instead add the ability
to send down raw JSON messages that are opaque to Tailscale but provide
the applications to define them however they wish.
Also update accessors to use the new values.

Allow calls to `WatchIPNBus` to be permformed by clients with
Readonly permissions. This brings it in line with the permissions
required for `Status`, which also exposes the similar information.
This allows clients to get realtime updates about the tailnet
in their own applications, without needing to actively poll the
`Status` endpoint.

On some platforms (notably macOS and iOS) we look up the default
interface to bind outgoing connections to. This is both duplicated
work and results in logspam when the default interface is not available
(i.e. when a phone has no connectivity, we log an error and thus cause
more things that we will try to upload and fail).
Fixed by passing around a netmon.Monitor to more places, so that we can
use its cached interface state.

We're using it in more and more places, and it's not really specific to
our use of Wireguard (and does more just link/interface monitoring).
Also removes the separate interface we had for it in sockstats -- it's
a small enough package (we already pull in all of its dependencies
via other paths) that it's not worth the extra complexity.

This change adds a ringbuffer to each magicsock endpoint that keeps a
fixed set of "changes"–debug information about what updates have been
made to that endpoint.
Additionally, this adds a LocalAPI endpoint and associated
"debug peer-status" CLI subcommand to fetch the set of changes for a given
IP or hostname.

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.
