Improve Windows version detection and LdrSystemDllInitBlock initialization

Browse Source 
- Add WINDOWS_VERSION enum and PS_SYSTEM_DLL_INIT_BLOCK sizes for WOW64 support across different Windows builds.
- Read system information (SystemRoot, BuildNumber, UpdateBuildRevision) from registry instead of hardcoded paths.
- Add build comparison helpers in process_context for precise build checks.
