Spiral Matrix IV

You are given two integers `m` and `n`, which represent the dimensions of a matrix. You are also given the `head` of a linked list of integers. Generate an `m x n` matrix that contains the integers in the linked list presented in **spiral** order **(clockwise)**, starting from the **top-left** of the matrix. If there are remaining empty spaces, fill them with `-1`. Return _the generated matrix_.   **Example 1:** **Input:** m = 3, n = 5, head = [3,0,2,6,8,1,7,9,4,2,5,5,0] **Output:** [[3,0,2,6,8],[5,0,-1,-1,1],[5,2,4,9,7]] **Explanation:** The diagram above shows how the values are printed in the matrix. Note that the remaining spaces in the matrix are filled with -1. ``` **Example 2:** **Input:** m = 1, n = 4, head = [0,1,2] **Output:** [[0,1,2,-1]] **Explanation:** The diagram above shows how the values are printed from left to right in the matrix. The last space in the matrix is set to -1. ```   **Constraints:** - `1 <= m, n <= 105` - `1 <= m * n <= 105` - The number of nodes in the list is in the range `[1, m * n]`. - `0 <= Node.val <= 1000`
