fixed marker generation in charuco board #25673

When generating  Charuco board markers in `generateImage()`, a problem occurs as in https://github.com/opencv/opencv/issues/24806, https://github.com/opencv/opencv/pull/24873:

This PR fixed this problems:

The test checks the inner and outer borders of the Aruco markers. In the outer border of Aruco marker, all pixels should be white. In the inner border of Aruco marker, all pixels should be black.
