Enable PDAF builds on JUPITER with NVHPC compilers (#150)
4d80f45 
## Pure PDAF

- **`BuildPDAF.cmake`**: Add NVHPC support

- **`BuildPDAFMODEL.cmake`**: Make `-lgfortran` conditional on GNU
compiler. Add GPU libraries for `ParFlowGPU` builds.

- **`BuildParFlow.cmake`**: Umpire is passed to ParFlow for
`ParFlowGPU+PDAF` builds

- **`models/parflow_pdaf`**: Update submodule `v3.14.1-pdaf` →
`v3.15.0-pdaf`, necessary update for GPU support

## OASIS (affects all coupled simulations)

- **`BuildOASIS3MCT.cmake`**: Add `make realclean` as configure step
