* \brief ActsULQInputGrad 算子原型（GEIR OpDef + InferShape/Verify，v2.0 图模式对外调用通路）
*
* x_grad = y_grad * clamp_min_mask * clamp_max_mask（逐元素门控乘法）
* v2.0：调用形态为图模式（GE 图，直调 ge::op::ActsULQInputGrad）。dtype 域：y_grad
* fp16/fp32；mask bool/fp16/fp32。合法组合 4 组（mask 浮点须与 y_grad 同 dtype
* 或为 bool），由 Tiling/Verify 校验；混合浮点组合已移除。

*@brief Returns y_grad * clamp_min_mask * clamp_max_mask (elementwise STE clamp gradient gate).
*@par Inputs:
*Three inputs, including:
* @li y_grad: An ND Tensor. Must be one of the following types: float16, float32.
* @li clamp_min_mask: An ND Tensor. Must be one of the following types: bool, float16, float32.
* @li clamp_max_mask: An ND Tensor. Must be one of the following types: bool, float16, float32. \n
*@par Outputs:
*x_grad: An ND Tensor. Must be one of the following types: float16, float32 (same as y_grad).
*@par Third-party framework compatibility
*Compatible with the MindSpore ULQ backward operator.
