变更摘要
本 PR 对 math/lerp/examples/test_aclnn_lerp.cpp 示例进行资源管理方式改造，将原先手动调用 aclDestroyTensor、aclrtFree、aclrtDestroyStream、aclrtResetDevice、aclFinalize 的清理流程，改为基于 C++ RAII（std::unique_ptr、std::shared_ptr）自动释放，从而与 math/is_finite、math/is_inf 示例风格保持一致。改动主要集中在资源类型定义、初始化与张量创建接口签名调整，以及删除函数末尾的手动清理代码。
主要改动
- 引入 RAII 资源类型别名：新增
StreamPtr、DeviceMemPtr、TensorPtr三个基于std::unique_ptr的类型别名，分别以aclrtDestroyStream、aclrtFree、aclDestroyTensor作为删除器，并新增<memory>、<type_traits>头文件。 - 调整
Init函数接口与实现：Init改为接收StreamPtr&及bool& initialized、bool& deviceSet引用，内部先用裸指针创建aclrtStream再通过stream.reset(rawStream)交给智能指针管理，同时记录初始化和设备设置状态。 - 调整
CreateAclTensor接口与实现：函数由接收裸指针改为接收DeviceMemPtr&与TensorPtr&，内部先申请裸指针再reset到智能指针，并新增aclCreateTensor返回空指针的错误检查。 - 使用
aclGuard自动执行设备反初始化：在main中新增std::shared_ptr<void> aclGuard，通过 lambda 在作用域结束时按状态调用aclrtResetDevice和aclFinalize。 - 删除手动资源清理并改用
.get()传递裸指针：移除函数末尾的aclDestroyTensor、aclrtFree、aclrtDestroyStream等手动释放逻辑，workspaceAddr改为DeviceMemPtr，并在aclnnLerpGetWorkspaceSize、aclnnLerp、aclrtSynchronizeStream、aclrtMemcpy等调用处改用.get()。
不准确？
