Integrate Locally-Built Third-Party Libraries with Visual Studio Projects

This PR enables building Ocean using Visual Studio projects with locally-built third-party libraries from the CMake build system.

Changes:

• Visual Studio Integration: Updated all .props files to reference reorganized third-party library structure with
  version-organized paths (e.g., libname\version\lib\win_x64_vc143_static_debug)
• DirectShow Support: Added DirectShow Base Classes to Windows third-party CMake builds
• Documentation: Added comprehensive guide for building Ocean with Visual Studio projects (Section 4 in building_for_windows.md)
• Temporary Workarounds: Disabled ocean/io/Signature.* (requires OpenSSL, not yet built)
• Build Improvements: Updated .gitignore for build artifacts

Key Features:

• Third-party libraries built via CMake can now be used with Visual Studio projects
• Reorganization script transforms CMake output to Visual Studio-compatible structure
• Symlink approach ($(OCEAN_DEVELOPMENT_PATH)\3rdparty) for flexible paths
• Supports both CMake builds (CI/automation) and Visual Studio builds (development/debugging)

Limitations:

• OpenSSL not yet included (SSL functionality unavailable)
• Google V8 not included (JavaScript interaction unavailable)
