Add SoA macros to CUDADataFormats/Common.

[ericcano]

PR description:

The SoA macros generate classes that subdivide externally allocated buffer in
columns with alignement adequate for GPUs (by default).
An test validates the SoA and provides usage example.

PR validation:

This PR provide new tools and does not interfere yet with current production code. The tools itself is validated with a test program.

A new Pull Request was created by @ericcano (Eric Cano) for master.

It involves the following packages:

• DataFormats/Common (core)

@cmsbuild, @smuzaffar, @Dr15Jones, @makortel can you please review it and eventually sign? Thanks.
@makortel, @wddgit, @rovere this is something you requested to watch as well.
@perrotta, @dpiparo, @qliphy you are the release manager for this.

Thanks @ericcano. DataFormats/Common is not a good place for this code though, because it would add a dependence on Eigen, and, if I understood correctly, currently these SoAs can not be stored in ROOT.

Given the dependence on Eigen, even a new package could be the justified. I presume the intention would be to use the SoA's also in pure host code (without any dependence on CUDA), the best placement would likely still be under DataFormats (even if for now the Event products using the SoA's would be transient). There is a strong connection to GPUs, so perhaps the package would be best placed under heterogeneous category for review and maintenance.

Pull request #35951 was updated. @cmsbuild, @smuzaffar, @Dr15Jones, @makortel can you please check and sign again.

[makortel]

@ericcano Would you be able to present this model of building SoAs in the core software meeting on next Tuesday (Nov 9) or on the following week (Nov 16)?

[ericcano]

@makortel Yes, next Tuesday is fine.
Regarding the location, I will move all to CUDADataFormats/Common

I think this PR has been superseded by all the development work merged in 12.5.x and 12.6.x, up to #39319 .

@ericcano, do you agree this one could be closed ?
