First pass Texture Array support on CUDA/CPU (#1225)

* Add cubemap support.

* Add CUDA fence instrinsics.

* Added Gather for CUDA.

* Use the CUDA driver API as much as possible.

* * Support 1D texture on CPU
* WIP on 1D texture on CUDA
* Added simplified texture test

* Fix test.

* Improve texture-simple tests.

* * Add CPU support for 3d textures
* Add support for mip maps to CUDA
* Disable warnings in nvrtc
* Update CUDA docs

* WIP on 3d texture support.

* Add support for 3d textures for CPU and CUDA.

* CPU and CUDA support for cube maps.

* Add CPU support for Texture1DArray.

* Support CUDA Layered/Array type in meta library.
