refactor(hashtable): 简化哈希表初始化接口并优化文件打开模式
- 将哈希表初始化从两步设置改为一步完成,直接传递哈希函数和比较函数 - 重构scc_hashtable_init函数签名,接受函数指针参数 - 更新内部字段名从key_cmp为cmp_func以保持一致性 - 添加类型定义scc_hashtable_hash_func_t和scc_hashtable_equal_func_t - 修改PAL层文件操作接口,使用枚举模式替代固定只读模式 - 更新IR上下文、预处理器宏表等组件使用新的初始化方式 - 移除AST头文件中未使用的语义分析回调类型定义 - 修复预处理器中的空指针访问问题
