feat(mlirlite): 补齐 Debug Info 同形 API，导出名集与 llvmlite 一致(215=215)
- __module.vp: 新增 DINode/DINamedMeta 类、LLVMModule 追加 6 个 DI 字段(96->144B)、module_add_di_node/module_add_named_metadata 及实例方法、DI_NODE_SIZE/DI_NAMED_SIZE - __function.vp: Function 追加 DbgRef(80->88B) + function_set_dbg - __builder.vp: IRBuilder 追加 DbgLoc(32->40B) + set/clear_debug_location 方法 + 顶层 builder_set/clear_debug_location - __init__.vp: 导出上述 7 个 DI 名字，恢复与 llvmlite 的逐名同形(215=215) - MLIR 打印阶段忽略 DI：LLVMModulePrint 不输出 !N 元数据、_emit 不读 DbgLoc，保持 MLIR 语法合法（DI 只记录不输出） - README: 记录 DI 为「同形保留/只记录不输出」，名字数更新为 215
