bug #59845: Initialize newton, steffenson solvers with GSL_FN_FDF_EVAL_F_DF

These were the only places in these two solvers where GSL_FN_FDF_EVAL_F or GSL_FN_FDF_EVAL_DF were used independently. If the function or its derivative shared some expensive calculations in common, then this could lead to inefficient initialization of the solver.
