Add support for IFI on Ursa

[SamuelTrahanNOAA]

• Fixes Port libIFI and UPP-IFI connection to Ursa #1234

This PR adds support for generating IFI products on Ursa.

1. Remove IFI support on Hera from UPP. (Does not affect building IFI outside UPP.)
2. Update libIFI.fd hash to one that knows about the IntelLLVM cmake compiler ID.
3. Add modulefiles for linking with an external IFI library.
4. Add modulefiles for testing IFI in the regression tests (netcdf-cxx4)
5. Add regression tests for IFI. (Duplicate of Hera tests.)
6. Use C compiler ID instead of Fortran to detect the compiler flag to enable C++ libraries in Fortran when using the strange ifort + icpx combination.

@BenjaminBlake-NOAA - Conceivably, I could remove Hera support for IFI in this PR, as you requested. Should I do that in this PR?

• Remove UPP support for Hera #1255

[BenjaminBlake-NOAA]

@SamuelTrahanNOAA Yes, I think you can remove Hera support for IFI as part of this PR. Thanks

[SamuelTrahanNOAA]

I've removed IFI support on Hera, but not all UPP Hera tests. Your issue requests that all UPP Hera support be removed. Non-IFI tests are outside the scope of this PR.

Yes that's fine, the removal of the other Hera tests can be handled in a separate PR.

@SamuelTrahanNOAA We will wait until the dependent IFI PR is merged before moving forward with processing this PR.

Earlier this year we actually replaced all of the fv3r regression tests in UPP with RRFS tests (see PR #1258 ). The fv3r tests are an older version of the RRFS test which use a smaller (CONUS) domain. So I think the ifi_standalone_fv3r test may not be needed and can be removed.
