Add SIMD_FORCE_SCALAR macro #26

Selects scalar and turns off compilation of intrinsics. This is functionality that has been requested by multiple STK users as a workaround when intrinsics fail to compile.

STK users have also requested a "use scalar" macro for debugging and development purposes. I know in most cases it was sufficient to have that macro at the STK level, meaning that kokkos-simd was still compiling whichever intrinsics were available but we were only "selecting" scalar at the stk level. But this seems even better, to have the kokkos-simd compilation not even look at the intrinsics in that case.
