Further Enhancements to Recall Games Installed With DLC Unlockers

- Rename JSON Proxy field to "Proxy DLL Name" and always store the resolved
  name instead of null for default convention
- Add DetectInstalledProxy() to find proxy dlls winmm/winhttp/version.dll
- Fixes to ensure all detected unlockers are persisted in installed.json on scan so pre-existing unlockers are tracked even if not installed via CreamInstaller
- Restore proxy and extra protection state from saved records for both
  scanned and previously scanned games on reload
- Detect proxy DLLs from disk for previously scanned game reconstruction
