feat(ast): 添加内置表达式支持并完善解析器功能

- 添加SCC_AST_EXPR_BUILTIN枚举值用于表示内置表达式
- 定义scc_ast_builtin_expr_type_t枚举包含va_start、va_end、va_copy、va_arg等内置函数类型
- 在AST表达式结构中添加builtin字段以支持内置表达式存储
- 实现scc_ast_decl_unsafe_val_init内联函数用于不安全的声明初始化
- 修改sizeof和alignof表达式初始化函数以支持类型或表达式参数
- 修复默认语句的字段引用错误(default_stmt而非case_stmt)
- 改进词法分析器对整数字面量后缀(U、L、LL等)的处理逻辑
- 重构解析器中的声明解析逻辑,统一使用scc_parse_declarator函数
- 完善结构体、联合体和枚举类型的声明解析,支持仅有名称的前向声明
- 优化初始化列表解析,支持复合字面量的成员访问语法
- 更新参数类型列表解析以正确处理参数声明
- 修复括号表达式的解析逻辑,区分类型转换和普通括号表达式
