Feat: Zig build to faster building pipy

[xiaods]

Comparison with CMake

Advantages of Zig build system:

1. Single tool: No need for CMake, Make, Ninja, etc.
2. Cross-compilation: Easy cross-compilation to different targets
3. Reproducible builds: Consistent builds across platforms
4. Fast incremental builds: Efficient caching system
5. Simpler syntax: More readable build configuration
6. Built-in package manager: Easy dependency management

Migration notes:

• The Zig build system produces the same output as CMake
• All CMake build options have Zig equivalents
• OpenSSL still requires external build (same as CMake)
• Version information is generated the same way
