Updates to the SmartSim build process:
- SmartSim can now be built using Cuda version 11.8 or Cuda 12.1 by
specify `smart build --device=cuda118` or `smart build
--device=cuda121`. The original `smart build --device=gpu` will default
to using Cuda 11.8.
- As a result of the previous change, SmartSim now requires C++17 and a
minimum Cuda version of 11.8 in order to build Torch 2.1.0.
- In addition this PR now uses Torch 2.1 and TF 2.14/2.15 (for CUDA 11.8/12.1 respectively)

The existing dockerfiles did not have the necessary environments to
enable GPU support for users wanting to run the tutorials. Two
Dockerfiles (for CUDA 11.8 and 12.1) are provided. Note that this has
only been tested on a workstation and no HPC support should be expected
at this time.
