Fixes tailscale/corp#18441
For a few days, IsMacAppStore() has been returning `false` on App Store builds (IPN-macOS target in Xcode).
I regressed this in #11369 by introducing logic to detect the sandbox by checking for the APP_SANDBOX_CONTAINER_ID environment variable. I thought that was a more robust approach instead of checking the name of the executable. However, it appears that on recent macOS versions this environment variable is no longer getting set, so we should go back to the previous logic that checks for the executable path, or HOME containing references to macsys.
This PR also adds additional checks to the logic by also checking XPC_SERVICE_NAME in addition to HOME where possible. That environment variable is set inside the network extension, either macos or macsys and is good to look at if for any reason HOME is not set.
Mostly inconsequential minor fixes for consistency. A couple of changes
to actual JSON examples, but all still very readable, so I think it's
fine.

We can safely disable the App Sandbox for our macsys GUI, allowing us to use `tailscale ssh` and do a few other things that we've wanted to do for a while. This PR:
- allows Tailscale SSH to be used from the macsys GUI binary when called from a CLI
- tweaks the detection of client variants in prop.go, with new functions `IsMacSys()`, `IsMacSysApp()` and `IsMacAppSandboxEnabled()`

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.

According to
https://learn.microsoft.com/en-us/windows/win32/msi/standard-installer-command-line-options#promptrestart,
`/promptrestart` is ignored with `/quiet` is set, so msiexec.exe can
sometimes silently trigger a reboot. The best we can do to reduce
unexpected disruption is to just prevent restarts, until the user
chooses to do it. Restarts aren't normally needed for Tailscale updates,
but there seem to be some situations where it's triggered.

This fixes a bug that was introduced in #11258 where the handling of the
per-client limit didn't properly account for the fact that the gVisor
TCP forwarder will return 'true' to indicate that it's handled a
duplicate SYN packet, but not launch the handler goroutine.
In such a case, we neither decremented our per-client limit in the
wrapper function, nor did we do so in the handler function, leading to
our per-client limit table slowly filling up without bound.
Fix this by doing the same duplicate-tracking logic that the TCP
forwarder does so we can detect such cases and appropriately decrement
our in-flight counter.

There are container environments such as GitHub codespaces that have
partial IPv6 support - routing support is enabled at the kernel level,
but lacking IPv6 filter support in the iptables module.
In the specific example of the codespaces environment, this also has
pre-existing legacy iptables rules in the IPv4 tables, as such the
nascent firewall mode detection will always pick iptables.
We would previously fault trying to install rules to the filter table,
this catches that condition earlier, and disables IPv6 support under
these conditions.

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.
