Let's convert this #LVGL App from C to #ZigLang

https://github.com/lupyuen/zig-lvgl-nuttx#lvgl-test-app-in-c

Apache #NuttX RTOS compiles our #LVGL App with these GCC Options ... We'll pass the same options to #ZigLang Compiler

#ZigLang Compiler can Auto-Translate C programs into Zig ... Let's do it for our #LVGL App

https://github.com/lupyuen/zig-lvgl-nuttx#auto-translate-lvgl-app-to-zig

#ZigLang Compiler can't import C Structs containing Bit Fields (yet) ... So we handle these special structs in C instead of Zig
