feat(ast): 添加汇编器模块并改进AST定义和IR转换

Browse Source 
- 在README.md中添加asm汇编器模块说明
- 更新ast_def.h中的枚举注释，添加sema相关信息以明确语义分析作用域
- 重命名函数参数param_types为params，使命名更清晰
- 移除call表达式中的_target字段，简化结构
- 为member、identifier等字段添加///< fill by sema注释说明填充时机
- 为jump语句添加_target字段用于语义分析
- 更新所有AST初始化函数，接受位置信息参数以改进错误定位
- 修复alignof表达式的类型应为ALIGN_OF而非SIZE_OF的问题
- 重构ast2ir.h，引入scc_ast2ir_ctx_t上下文结构体统一管理转换状态
- 添加符号表、节点到IR映射等必要的转换上下文信息
