feat(nvidia_hpc): support C/C++ -std

[e-kwsm]

The author has only NVIDIA 22.9.0, so information on older versions is missed.

For example, https://docs.nvidia.com/hpc-sdk/archive/20.7/hpc-sdk-release-notes/index.html#platform-requirements shows requirements but NVIDIA’s C/C++ support status is missed.

Seems like old releases can be found here: https://developer.nvidia.com/nvidia-hpc-sdk-releases

I looked at the online docs for the oldest version listed there, which claims nvc++ is a C++17 compiler, and nvc is a C11 compiler.

BTW the commit message confuses me, not sure how to read the domain of interest. Maybe the commit title prefix should be nvidia_hpc compiler:?

[dcbaker]

@e-kwsm can you update the commit message to something like compilers/nvidia_hpc: support C/C++ -std?

I'll merge this with that done.
