Message : Remove several underused platform configs. * Removes D3D11 Warp and Reference configs from tests. * Removes several permutations of OpenGL back-end specific configs. * Removes FL 9_3 since it is no longer supported. * Removes present path "Copy" since it's redundant with normal D3D11. Reduces number of configs from over 60 to 25.
