Updated Pangea3 host config with C++17 standard

[sframba]

Companion PR to GEOS' PR #2910, this PR updates the Pangea 3 host config file after upgrade od cuda to version 11.5 on this machine. In particular,

• The c++ standard is set to c++17 (as it should be for GEOS)
• The default hypre implementation on the machine is set to CPU (GPU not supported for all applications) hypre with cuda acceleration seems to be mostly working now
• A flag allowing host constexpr call form device code is added, reducing warnings
• CUpti profiling via Caliper is enabled by default

Hi Stefano, can you share which models don't work with hypre GPU?

Hi Stefano, can you share which models don't work with hypre GPU?

Hi @victorapm , this was the way we used to compile everything on Pangea 3 (Power9 CPUs with Nvidia V100+ nvcc 11.0.3), we had some issues with some solvers such as CompositionalMultiphaseFVM . We haven't tested with the latest versions of hypre. Let me put this on hold while I test the latest TPLs on Pangea3

Hi Stefano, can you share which models don't work with hypre GPU?

Hi again @victorapm, it seems that with the latest version of hypre, one of the GEOS unit tests still fails on Pangea3: testExternalSolvers, with only one test failing: Hypre/SolverTestLaplace2D/0.GMRES_ILU.
Still, the flow simulation that was holding us back seems to be working now, so I'll re-enable hypre cuda acceleration by default in this PR

Thanks, Stefano! I will check with @castelletto1 about the failing test
