numel 中英文 API 文档是不是也应该体现这一点修改？

Description
Pcard-75624
为eager Tensor添加
__cuda_array_interface__属性，从而允许paddle.Tensor被不同的GPU计算框架在同相同设备上以零拷贝的方式使用。添加对应单测。属性定义规范参考：https://numba.readthedocs.io/en/0.52.0/cuda/cuda_array_interface.html(与其他框架对齐，采用version 2而非version 3)
代码参考:
Support the __cuda_array_interface__ protocol tensorflow/tensorflow#29039
Add paddle backend NVIDIA/warp#313

paddle.numel支持uint8和int8类型，添加对应单测。
