WIP on RWTexture types on CUDA/CPU (#1234)

* CUDA support for array of resources.

* * Add support for Texture2DArray on CPU
* Expand texture-simple.slang to test Texture2DArray

* Reorganise CUDAComputeUtil to split out createTextureResource.

* Add TextureCubeArray support for CPU/CUDA targets.

* Pulled out CUDAResource
Renamed derived classes to reflect that change.

* Creation of SurfObject type.

* Functions to return read/write access for simplifying future additions.

* WIP for RWTexture access on CPU/CUDA.

* CUsurfObject cannot have mips.

* Ability to set number of mips on test data.
Preliminary support for CUsurfObj and RWTexture1D on CUDA.
CUDA docs improvements.

* Fix typo.
