refactor(ast2ir): 提取模块访问函数并优化类型大小计算

Browse Source 
- 添加 scc_ast2ir_mir_module 内联函数统一访问模块
- 替换所有直接访问 ctx->builder.cprog->module 的地方
- 移除重复的 scc_hir_type_size 函数实现
- 添加 scc_hir_module_type_size 函数到模块接口
- 更新所有类型大小计算调用使用新函数

feat(hir): 增强构建器安全性和全局变量处理

- 为 scc_hir_builder_integer 添加空指针检查断言
- 修复 scc_hir_builder_global_alloca 中全局变量类型设置
- 改进 scc_hir_builder_get_elem_ptr 处理空指针索引情况
- 重构字符串常量生成使用 get_elem_ptr 构建器函数

refactor(lir): 简化地址表达式表示并增强内置函数支持

- 移除复杂地址结构体 scc_lir_addr_t
- 简化 scc_lir_instr 结构体中的地址表示
- 移除 STORE_ADDR 操作码
- 添加 memcpy 和 memset 内置函数操作码
- 在符号元数据中使用联合体替代嵌套结构体

feat(hir2lir): 完善 HIR 到 LIR 转换中的内置函数处理

- 添加 ensure_vreg 辅助函数确保虚拟寄存器操作数
- 正确处理全局变量地址符号引用
- 优化 GET_ELEM_PTR 转换使用类型大小计算
- 完整实现所有内置函数(BUILTIN)的 LIR 转换
- 包括 memcpy、memset、va_start、va_arg、va_end、va_copy 等
