Document z_moji.c (#926)
* Document `z_moji.c` * Run formatter * Use `CHAR_HEIGHT` instead of `CHAR_WIDTH` for y pos * `> X - 1` -> `>= X` * `const char*` for string argument * Type palettes and textures with `u64` * Remove unused variable * Use `CHAR_WIDTH` and `CHAR_HEIGHT` more * Explicit documentation on `gMojiFontTex`
