Stokhos: avoid deprecation warnings when compiling with cuda >= 10.0

Enhancement

Many deprecation warnings are issued when compiling Stokhos with cuda >= 10.0. The deprecation warnings come from including math_functions.h in stokhos/src/sacado/kokkos/vector/Sacado_MP_Vector_ops.hpp. The deprecation warnings suggest to include cuda_runtime_api.h instead.

We have implemented the following patch:
