fix: use vcpkg for Windows OpenSSL instead of vendored compilation

- Remove Windows GNU target (x86_64-pc-windows-gnu)
- Switch from Strawberry Perl + vendored OpenSSL to vcpkg approach
- Install pre-built static OpenSSL libraries via vcpkg for Windows
- Use architecture-specific vcpkg packages (x64/arm64-windows-static)
- Keep vendored OpenSSL for Unix platforms (Linux/macOS)
- This eliminates all Perl module compilation issues on Windows
