NVProfilerService: improve handling of module prefetching

[fwyzard]

The display of module prefetching calls is now optional, controlled by the showModulePrefetching parameter.
In the Visual Profile prefetching shows up as light green (or light amber for highlighted modules) to easily distinguish it from the actual event processing.

A new Pull Request was created by @fwyzard (Andrea Bocci) for master.

It involves the following packages:

HeterogeneousCore/CUDAServices

@cmsbuild, @smuzaffar, @Dr15Jones can you please review it and eventually sign? Thanks.
@makortel this is something you requested to watch as well.
@davidlange6, @slava77, @fabiocos you are the release manager for this.

Comparison job queued.

[fwyzard]

Note: this works locally, but it will likely fail to build, since the linker check will fail without CUDA installed.

[smuzaffar]

@fwyzard , I noticed that we get this build error (which is then ignored by the edmWriteConfig).

@@@@ Running edmWriteConfigs for HeterogeneousCoreCUDAServicesPlugins
error: edmWriteConfigs caught an exception while loading a plugin library.
The executable will return success (0) so scram will continue,
but no cfi files will be written.
An exception of category 'PluginLibraryLoadError' occurred.

we missing the cuda/lib64/stub in LD_LIBRARY_PATH, was it on purpose?

[fwyzard]

Indeed, that's what you need scram setup nvidia-drivers for.

The stubs are used by the link step of the compilation, but are not used at run time, since they do not provide any functionality.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
