Add support for some NVCC compilation switches as CUDA features

C and C++ have multiple features supported in CMake below the level of the standard version. The same should be the case for CUDA. NVCC has offered, for nearly a decade now, the options:

--no-host-device-initializer-list               (-nohdinitlist)                 
        Do not implicitly consider member functions of std::initializer_list as __host__
        __device__ functions.

--no-host-device-move-forward                   (-nohdmoveforward)              
        Do not implicitly consider std::move and std::forward as __host__ __device__
        function templates.

--expt-relaxed-constexpr                        (-expt-relaxed-constexpr)       
        Experimental flag: Allow host code to invoke __device__ constexpr functions,
        and device code to invoke __host__ constexpr functions.Note that the behavior
        of this flag may change in future compiler releases.

--extended-lambda                               (-extended-lambda)              
        Allow __host__, __device__ annotations in lambda declaration. 

These should correspond to CMake CUDA features:

cuda_host_device_initializer_list
cuda_host_device_move_forward
cuda_relaxed_constexpr
cuda_extended_lambda

which control whether or not the relevant switch is passed to NVCC.

(I don't know what clang supports w.r.t. CUDA compilation, that might have some bearing on this issue.)
