Add Security OSStatus error codes

[paulmgeurts]

Summary

• Add a Security error domain with common errSec OSStatus values from Apple's SecBase.h.
• Cover Security lookups with code-only and domain-qualified tests.

Issue Addendum

Addresses AvdLee/RocketSimApp#1021 from the RocketSim low-effort audit. The RocketSim app consumes this utility through the WhatTheErrorCode package, so the database change belongs upstream rather than in the RocketSim app repository.

Verification

• PASS: env CLANG_MODULE_CACHE_PATH=/private/tmp/WhatTheErrorCode-1021-clang-cache swift test --scratch-path /private/tmp/WhatTheErrorCode-1021-build
• NOTE: plain swift test first failed in this sandbox because SwiftPM attempted to write the manifest/module cache under the home directory; rerunning with temp cache paths succeeded.
