[HIPIFY][SWDEV-490433][fix] Add support for cuda-samples helper headers to HIP

[ranapratap55]

cuda-samples/* requires helper header files.
Fixes SWDEV-490433

Please regenerate hipify-perl and docs according to the instructions and add them to this PR. The needed tests I'll add in a separate PR.

@ranapratap55,

Could you also provide here the statistics on CUDA Samples where helper includes are not provided explicitly in the sources? It is needed to figure out the necessity for implementing nvcc's behaviour with implicitly added includes in hipify-clang. We discussed it separately, and I need to be sure that it is quite a regular situation to implement on our side as well.

Thanks

In CudaMath.h header file colorSums() uses float3 as input and it is implemented in helper_math.h.

The header CudaMath.h do not include helper_math.h in source. But it is included in the main source dxtc.cu file.

Ok, this is an implicit nvcc include case, but only one. Do you have more evidence?

There are multiple cuda-samples requires inclusion of those helper_* files. Below are few examples which I found while debugging requires including helper_* headers. I believe there are many more files which require those inclusions, and it is better we implement the generic solution as we might encounter these issues regularly.

1. bodysystemcpu_impl.h
2. MonteCarlo_reduction.cuh
3. fastWalshTransform_kernel.cuh
4. bicubicTexture_kernel.cuh

Regenerated the hipify-perl and docs.

LGTM, thanks!
