New modules for Bridges2 GPU

[sbryngelson]

It seems the previous modules for Bridges2 are no longer working. I found these to work:

  1) openmpi/4.0.5-nvhpc22.9   2) python/3.8.6   3) cuda/11.7.1

along with an

export FC=nvfortran
export CC=nvc
export CXX=nvc++

Update: Related to #613 . I found that the above works when turning set(NVHPC_USE_TWO_PASS_IPO TRUE) to set(NVHPC_USE_TWO_PASS_IPO FALSE) in CMakeLists.txt, but does not work if twopassIPO is TRUE. This serves as a confirmation that at least nvhpc 23.X is required for two-pass IPO.

Briges2 does not have nvhpc23.X so I cannot test with these
