Allows one to replace the GPU array in a dense matrix with an array provided by the user. This is useful to avoid copying an array into a matrix

This permanently replaces the GPU array and frees the memory associated with the old GPU array.
The memory passed in CANNOT be freed by the user. It will be freed
when the matrix is destroyed. The array should respect the matrix leading dimension.
