Add checks for NVIDIA's CUDA compiler

Browse Source 
- Disable templated user-defined literals when compiled under nvcc

Similarly to Intel's C++ compiler, nvcc fails to compile templated UDLs
as they both share the same parsing engine (EDG C++ Front End).  This
fixes building CUDA programs which make use of fmt.
