feat(ast2ir): 实现C11类型提升系统并重构HIR基本块管理

Browse Source 
- 新增 scc_ast2ir_promote.c 实现整数提升(6.3.1.1)和寻常算术转换(6.3.1.8)
- 重构 HIR Builder: bblock → create_bblock + append_bblock，引入BBList链表管理
- AST2IR 全面集成类型提升：二元运算、赋值、函数调用参数、自增/自减操作符
- 变参函数支持：跳过 ... 假参数，实现默认参数提升(float→double等)
- 简化 HIR Dump 实现
- MIR: Win64 ABI改进、x86指令选择优化
- 新增 printf 测试用例
