Update CUDAUtilities from the Patatrack development

[fwyzard]

PR description:

Introduce an STL-compatible allocator for CUDA host memory.

Remove dependency on NVIDIA cub.

Replace the use of the prefix scan from cub with a home-brewed implementation, using dynamic instead of static shared memory.

Annotate all CMS-specific changes to CachingDeviceAllocator.

No changes to physics or timing performance.

PR validation:

See cms-patatrack#447 and cms-patatrack#449.
