A filesystem was plumbed into netstack in 993acf4475b22d693
but hasn't been used since 2d5d6f5403f3. Remove it.
Noticed while rebasing a Tailscale fork elsewhere.

In this PR, we add the tailscale syspolicy command with two subcommands: list, which displays
policy settings, and reload, which forces a reload of those settings. We also update the LocalAPI
and LocalClient to facilitate these additions.

Now when we have HA for egress proxies, it makes sense to support topology
spread constraints that would allow users to define more complex
topologies of how proxy Pods need to be deployed in relation with other
Pods/across regions etc.

- `tailscale metrics print`: to show metric values in console
- `tailscale metrics write`: to write metrics to a file (with a tempfile
& rename dance, which is atomic on Unix).
Also, remove the `TS_DEBUG_USER_METRICS` envknob as we are getting
more confident in these metrics.

In this PR, we update the syspolicy package to utilize syspolicy/rsop under the hood,
and remove syspolicy.CachingHandler, syspolicy.windowsHandler and related code
which is no longer used.
We mark the syspolicy.Handler interface and RegisterHandler/SetHandlerForTest functions
as deprecated, but keep them temporarily until they are no longer used in other repos.
We also update the package to register setting definitions for all existing policy settings
and to register the Registry-based, Windows-specific policy stores when running on Windows.
Finally, we update existing internal and external tests to use the new API and add a few more
tests and benchmarks.

In f77821fd63 (released in v1.72.0), we made the client tell a DERP server
when the connection was not its ideal choice (the first node in its region).
But we didn't do anything with that information until now. This adds a
metric about how many such connections are on a given derper, and also
adds a bit to the PeerPresentFlags bitmask so watchers can identify
(and rebalance) them.

Adds a new blockblame package which can detect common MITM SSL certificates used by network appliances. We use this in `tlsdial` to display a dedicated health warning when we cannot connect to control, and a network appliance MITM attack is detected.

Adds logic to `checkExitNodePrefsLocked` to return an error when
attempting to use exit nodes on a platform where this is not supported.
This mirrors logic that was added to error out when trying to use `ssh`
on an unsupported platform, and has very similar semantics.

* updates to LocalBackend require metrics to be passed in which are now initialized
* os.MkdirTemp isn't supported in wasm/js so we simply return empty
string for logger
* adds a UDP dialer which was missing and led to the dialer being
incompletely initialized
