546 update cmakeliststxt to support latest cuda project type and architectures

[mwaxmonsky]

Simplifies CMake infrastructure by removing openACC support and modernizes CUDA integration with CMake.

Closes #546

Lots of red. Beautiful! and I like the completeness of the architectures

I wanted more red but CMake isn't quite there for CUDA yet. :(

I also was thinking would it make sense to add a default architecture if none is provided (ie. if MICM_GPU_TYPE is not set but MICM_ENABLE_CUDA is, maybe set MICM_GPU_ARCH=all-major?) (https://cmake.org/cmake/help/latest/prop_tgt/CUDA_ARCHITECTURES.html)

Thanks @sjsprecious!

@K20shores, when you have a sec, could you take another look at these changes? We changed some of the core logic a bit more and just wanted to make sure it looked okay to you.
