Revert to CUDA 10.1 Update 1 (10.1.168), add support for Power (11.0.x backport)

[fwyzard]

Backport of #5418.

CUDA 10.1 Update 2 and later show a problem with running under MPS (NVIDIA Multi Process Server) or using CUDA Dynamic Parallelism within CMSSW.
While awaiting feedback from NVIDIA, the only solution seems to revert to the latest working version, which was 10.1 Update 1.

Drop the Nsight Compute and Nsigh System tools from the CUDA package, because they are released much more often as external packages.

Add support for CUDA on IBM Power architecture (ppc64le) on Linux.

@smuzaffar is this

please test for slc7_ppc64le_gcc820

correct ?
There was not message about additional tests for it.

[fwyzard]

enable gpu

[smuzaffar]

@fwyzard , one needs to explicitly enable additional tests

[fwyzard]

@fwyzard , one needs to explicitly enable additional tests

I am sorry but I do not understand what that means, concretely.
Do you mean that I have to ask @cmsbot something different ?
Or do you mean that we do not support additional tests on slc7_ppc64le_gcc820 ?

If the latter, does it mean that @cmsbot will still run some basic tests ?
Or that it is not currently possible to run tests on slc7_ppc64le_gcc820 from a PR ?

Bottom line is, please test this PR for

• Intel/AMD (x86_64) on cc7and cc8
• Power (ppc64le) on cc7
• ARM (aarch64) on cc7
• with GPU tests when/where possible

Thank you!

backport looks consistent with the update in master
