feat(abi): 新增ABI类型布局描述接口和Windows x64实现

Browse Source 
- 新增scc_abi包，包含基础类型布局描述接口
- 实现Windows x64 ABI类型布局计算功能
- 定义基本类型枚举和布局信息结构体
- 提供类型布局计算的核心接口函数

refactor(ast2ir): 使用新的ABI接口替换旧的类型转换实现

- 将旧的scc_type_abi_t替换为新的scc_abi_type_calc_t
- 更新AST到IR的类型转换逻辑，使用新的ABI计算接口
- 修改上下文初始化和类型解析相关代码
- 移除废弃的头文件和相关实现

refactor(ir): 统一IR节点引用类型命名并完善构建器功能

- 将scc_ir_node_ref_vec_t重命名为scc_ir_value_ref_vec_t保持一致性
- 更新聚合类型的字段名称从elements到fields
- 添加全局变量分配构建器函数scc_ir_builder_global_alloca
- 清理构建器中多余的注释和代码
