feat(cbuild): 更新项目配置以支持HIR中间表示

Browse Source 
- 统一包名格式化，添加空格对齐
- 将依赖项从ir和lir重命名为hir，移除lir注释
- 为ast2ir模块添加正确的包名称"scc_ast2ir"
- 更新依赖引用路径指向新的HIR库结构
- 移除注释掉的ir2mcode和sccf2target依赖项

refactor(ast2ir): 迁移到HIR中间表示替换IR表示

- 更新头文件包含，使用hir_builder.h替代ir_builder.h
- 修改上下文结构体，将scc_ir_builder_t替换为scc_hir_builder_t
- 更新函数签名，将参数类型从scc_ir_*转换为scc_hir_*
- 调整返回值类型，将scc_ir_value_ref_t和scc_ir_type_ref_t
  分别替换为scc_hir_value_ref_t和scc_hir_type_ref_t
- 重新排列头文件包含顺序以满足依赖关系
