In this PR, we implement (but do not use yet, pending #13727 review) a syspolicy/source.Store
that reads policy settings from environment variables. It converts a CamelCase setting.Key,
such as AuthKey or ExitNodeID, to a SCREAMING_SNAKE_CASE, TS_-prefixed environment
variable name, such as TS_AUTH_KEY and TS_EXIT_NODE_ID. It then looks up the variable
and attempts to parse it according to the expected value type. If the environment variable
is not set, the policy setting is considered not configured in this store (the syspolicy package
will still read it from other sources). Similarly, if the environment variable has an invalid value
for the setting type, it won't be used (though the reported/logged error will differ).

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 this PR we add syspolicy/rsop package that facilitates policy source registration
and provides access to the resultant policy merged from all registered sources for a
given scope.

With the upcoming syspolicy changes, it's imperative that all syspolicy keys are defined in the syspolicy package
for proper registration. Otherwise, the corresponding policy settings will not be read.
This updates a couple of places where we still use string literals rather than syspolicy consts.

We add package defining interfaces for policy stores, enabling creation of policy sources
and reading settings from them. It includes a Windows-specific PlatformPolicyStore for GP and MDM
policies stored in the Registry, and an in-memory TestStore for testing purposes.
We also include an internal package that tracks and reports policy usage metrics when a policy setting
is read from a store. Initially, it will be used only on Windows and Android, as macOS, iOS, and tvOS
report their own metrics. However, we plan to use it across all platforms eventually.

Adds the ability to start the backend by reading an authkey stored in the syspolicy database (MDM). This is useful for devices that are provisioned in an unattended fashion.

Package setting contains types for defining and representing policy settings.
It facilitates the registration of setting definitions using Register and RegisterDefinition,
and the retrieval of registered setting definitions via Definitions and DefinitionOf.
This package is intended for use primarily within the syspolicy package hierarchy,
and added in a preparation for the next PRs.

Previously, the "RunExitNode" policy merely controlled the visibility of
the "run as exit node" menu item, not the setting itself. This migrates
that setting to a preference option named "AdvertiseExitNode".

Updates ENG-2513. Renames client metrics keys used on Windows for consistency with Apple platforms.
Signed-off-by: Andrea Gottardo <andrea@tailscale.com>
Due to the Sparkle preference naming convention, macsys already has a
policy key named "ApplyUpdates" that merely shows or hides the menu
item that controls if auto updates are installed, rather than directly
controlling the setting.
For other platforms, we are going to use "InstallUpdates" instead
because it seemed better than the other options that were considered.

Previously, policies affected the default prefs for a new profile, but
that does not affect existing profiles. This change ensures that
policies are applied whenever preferences are loaded or changed, so a
CLI or GUI client that does not respect the policies will still be
overridden.
Exit node IP is dropped from this PR as it was implemented elsewhere
in #10172.

These policy keys are supported on Apple platforms in Swift code; in
order to support them on platforms using Go (e.g. Windows), they also
need to be recorded here.
This does not affect any code, it simply adds the constants for now.

This commit changes the PostureChecking syspolicy key to be a
PreferenceOption(user-defined, always, never) instead of Bool.
This aligns better with the defaults implementation on macOS allowing
CLI arguments to be read when user-defined or no defaults is set.
