 * \brief Eltwise operator definition
 *
 * Eltwise performs element-wise operations on 1~32 input tensors:
 *   mode=0 (PRODUCT): out[i] = x0[i] * x1[i] * ... * x_{n-1}[i]
 *   mode=1 (SUM):     out[i] = c0*x0[i] + c1*x1[i] + ... + c_{n-1}*x_{n-1}[i]
 *   mode=2 (MAX):     out[i] = max(x0[i], x1[i], ..., x_{n-1}[i])
 *
 * Input:  inputs (DYNAMIC_INPUT, 1~32 tensors, float16/bfloat16/float32)
 * Output: out (Tensor, same dtype/shape as inputs)
 * Attrs:  mode (int), coeff (listFloat)
 * Target: Ascend950 (arch35) only
