* @brief Pad a tensor.
* @par Inputs:
* Two inputs, including:
* @li x: A Tensor. Must be one of the following types: bfloat16, float16,
* float32, double, int32, uint8, int16, int8, complex64, int64, qint8,
* quint8, qint32, qint16, quint16, uint16, complex128, uint32, uint64, bool,
* hifloat8, float8_e5m2, float8_e4m3fn, float8_e8m0, float4_e2m1, float4_e1m2. Supported format list ["ND"].
* @li paddings: A Tensor of type int32 or int64. Supported format list ["ND"]. \n
* @par Outputs:
* y: A Tensor of the same type as "x". Supported format list ["ND"]. \n
* @li Due to different architectures, the calculation results of this operator
* on NPU and CPU may be inconsistent. \n
* @attention Constraints:
* If the type of x is float4_e2m1 or float4_e1m2, paddings values should be even number.
* If the type of x is hifloat8, float8_e5m2, float8_e4m3fn or float8_e8m0,
* paddings values should be non-negative integers. \n
* @par Third-party framework compatibility:
* Compatible with TensorFlow operator Pad.
