Nick Khyl	2336c340c4	util/syspolicy: implement a syspolicy store that reads settings from environment variables ... 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).

Nick Khyl	aeb15dea30	util/syspolicy/source: add package for reading policy settings from external stores ... 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.

Nick Khyl	67df9abdc6	util/syspolicy/setting: add package that contains types for the next syspolicy PRs ... 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.
