feat(ast): 更新AST dump功能以使用新的树转储接口

- 将头文件中的tree_dump.h替换为scc_tree_dump.h
- 修改函数签名将scc_tree_dump_ctx_t改为scc_tree_dump_t
- 移除过时的宏定义和内联函数实现
- 使用新的scc_tree_dump_* API替代旧的PRINT_*宏
- 简化类型、表达式、语句和声明的转储逻辑
- 统一使用新的树转储接口进行节点和值的输出

feat(ast2ir): 实现逻辑运算符和一元运算符的IR转换

- 添加scc_ast2ir_logical_expr函数处理&&和||运算符
- 实现短路求值逻辑,包含分支控制流
- 添加对一元正号运算符的支持
- 实现取地址和间接寻址运算符
- 添加字符字面量解析支持转义序列

fix(ir): 修复字符串常量构建中的长度计算错误

- 修正数组长度计算从len+1改为len-1
- 调整字符串内容复制逻辑跳过引号边界
- 修正内存分配大小与实际数据长度匹配

refactor(ir): 更新IR转储模块使用统一的树转储接口

- 将IR转储上下文中的tree_dump_ctx_t替换为scc_tree_dump_t
- 更新初始化函数签名以使用新的转储接口类型
