This commit implements layout_left in support of C++23 mdspan (https://wg21.link/p0009). layout_left is a layout mapping policy whose index mapping corresponds to the memory layout of Fortran arrays. Thus the left most index has stride-1 access, and the right most index is associated with the largest stride.
