CUDA support improvements (#1168)

* Add test result for compile-to-cuda

* Add RAII for some CUDA types to simplify usage.

* First pass handling of some instrinsics on CUDA (for example transcendentals)

* CUDA working with built in intrinsics.

* Add missing CUDA prelude intrinsics.

* CUDA matches CPU output on simple-cross-compile.slang

* First pass at hlsl-scalar-float-intrinsic.slang test.

* Fix smoothstep impl on CUDA and CPU.

* Fixed step intrinsic on CUDA/CPU.

* Added operator[] to Matrix for C++, to allow row access.
Needs a fix for CUDA.

* Fixed warning on clang build.
