+ * @brief Add ALiBi (Attention with Linear Biases) positional biases to the attention mask.
+ *
+ * This function computes the ALiBi slopes for each attention head (if max_bias > 0),
+ * multiplies them with the attention mask to produce bias tensors, and adds these biases
+ * to the destination tensor (@p dst).
+ *
+ * The function performs necessary broadcasting of the mask and slope tensors to match
+ * the shape of the destination tensor, then applies element-wise multiplication and addition
+ * using CANN operators.
+ *
+ * @param ctx         CANN backend context for memory management and operator execution.
+ * @param mask        Input attention mask tensor, assumed to be contiguous.
+ * @param dst         Destination tensor to which ALiBi biases will be added.
+ * @param dst_ptr     Pointer to the memory of the destination tensor.
+ * @param max_bias    Maximum bias value controlling the slope scaling.
+ *
+ * @note
+ * - Write data into dst_ptr using only the shape information of the dst tensor.
+ * - `GGML_MAX_DIMS + 2` is used to extend tensor dimensions for broadcasting.
