A matrix is Toeplitz if every diagonal from top-left to bottom-right has the same element.
Now given an M x N matrix, return True if and only if the matrix is Toeplitz.
Input: matrix = [[1,2,3,4],[5,1,2,3],[9,5,1,2]]
Output: True

In the above grid, the diagonals are "[9]", "[5, 5]", "[1, 1, 1]", "[2, 2, 2]", "[3, 3]", "[4]", and in each diagonal all elements are the same, so the answer is True.- matrix will be a 2D array of integers.
- matrix will have a number of rows and columns in range [1, 20].
- matrix[i][j] will be integers in range [0, 99].
