Setup of runtime cuda device (#1162)

* CUDA generated first test compiles.

* WIP on enabling CUDA in render-test.

* Detect CUDA_PATH environmental variable to build build cuda support into render-test.
Added WIP cuda-compute-util.cpp/h
Added  CUDA as a renderer type.

* Fix libraries needed for cuda in premake.

* Added -enable-cuda premake option. Defaults to false.

* Creates CUDA device, loads PTX and finds entry point.

* Fix some erroneous cruft from slang-cuda-prelude.h
