Description

• 新增了 CastDataTypeFunctor 针对 float8_e5m2、float8_e4m3fn、float16 和 bfloat16 到 complex<float>/complex<double> 的专门实现。
• 原本的泛型实现只做 static_cast<OutType>(in)，而 phi::dtype::complex<> 没有接受这些低精度实数类型的隐式转换，实际调用 TransDataType 做类型转换时会缺失对应路径或触发编译/运行错误。
• 现在在转换时先显式转成 float/double 再构造复数，就能让这些低精度实数张量安全地转换成复数张量，确保在需要复数输出（例如调用复数 kernel）时类型升级可以顺利执行。
• 编译时的错误日志：
