feat(ci):Add Windows 7 and LoongArch Release build support (#857)

- Add BuildWin7() function with patched Go compiler for Windows 7 compatibility
- Add BuildLoongOldWorld() function for linux-loong64-abi1.0 target
- Create Zig-based wrapper scripts for Windows 7 cross-compilation
- Integrate new build functions into existing release workflows
- Install MinGW-w64 cross-compilation toolchain for Win7 compatibility
- Replace Zig compiler wrappers with MinGW-w64 for Windows 7 builds
- Add Go build cache cleaning to prevent LoongArch ABI1.0/ABI2.0 cross-contamination
- Force clean rebuilds (-a flag) for LoongArch builds to ensure ABI compatibility
