These changes allow the OpenACC build on NSF NCAR's Derecho system by adding a new build target nvhpc-derecho and fixing some bugs. Also addresses some whitespace inconsistencies that may have hidden issues in mpas_dmpar.F.

NOTE: these changes have only been tested by building the atmosphere core without physics by commenting out the PHYSICS=-DDO_PHYSICS line in src/core_atmosphere/Makefile. This is the "moist dycore."

Files in core_atmosphere and core_init_atmosphere such as Fortran source
code, .gitignore, LICENSE, or others do not need execute permissions.
These occur in regions that are already commented out. If left in they
cause run time errors.

e.g. "Null pointer for temprbuffer (mpas_dmpar.F: 8618)"
Improve the use of whitespace for consistency and to help make some
blocks more clearly commented out. It can be difficult to tell what is
commented out or not when OpenACC directives are mixed in
