docker: add some tweaks to nvidia docker

[mloubout]

From @kenhester suggestions

Should fix issues with #2023 as cupy-cuda12x seems to install and work fine inside the image

To be discussed, do we keep nvidia-clang in CI

To be discussed, do we keep nvidia-clang in CI

Probably we can drop it

NVC for openmp offloading on NVidia cards
Amdclang for openmp offloading on AMD cards
icx for openmp offloading on Intel cards

That's completely fine by me

IIRC, we're still stuck with our own fork of clang, so one more reason to drop it.

Can we try again NVC + openmp offloading, now that we finally have NVC 23.5 ?

[georgebisbas]

I would vote for dropping as well...not popular, not faster, cumbersome for non-docker....
But will we also drop related infrastructure?

[mloubout]

Yes

Ok removing clang build and replacing by nvc
