feat(compiler): 启用 ir2mcode 和 sccf2target 库并实现 x86_64 代码生成

Browse Source 
- 在 cbuild.toml 中启用 ir2mcode 和 sccf2target 依赖库
- 修改 justfile 中的构建命令，使用 release 模式并更新 tokei 统计排除 mcode 目录
- 重构 LIR 中的地址操作数类型，将 SCC_LIR_INSTR_KIND_ADDR 重命名为 SCC_LIR_INSTR_KIND_MEM
- 实现完整的 MIR 到 x86_64 机器码转换，包括：
  - 添加 move、compare、binary operation 等指令发射函数
  - 实现条件分支和跳转指令生成
  - 支持算术、逻辑、移位等基本操作
  - 添加调用和返回指令处理
  - 实现栈分配和寄存器分配功能
- 完善 ir2mcode 模块，将 MIR 指令转换为机器码
- 更新 ir2sccf 模块，集成机器码生成功能
- 添加 mcode 库的架构支持和内存管理功能
- 修复 PE 文件生成中的空指针检查问题
