Add explicit interfaces for BACIO and g2 routines to remove Intel #8889 warnings

[mingchen-NOAA]

Pull Request Summary

This PR addresses Intel warning #8889: Explicit declaration of the EXTERNAL attribute is required by adding explicit interface blocks for all NCEP libraries BACIO and GRIB2 (g2) routines used in ww3_grib program. The warnings are successfully removed during debug build in both WW3 and operational workflows.

Description

This PR adds explicit interface blocks for all NCEP BACIO and GRIB2 (g2) routines used in ww3_grib.F90, eliminating Intel #8889 warnings in debug builds and preventing potential runtime mismatches. Because the installed BACIO library does not export a module file, USE BACIO_MODULE cannot be applied; therefore, explicit interfaces are required for safe, type-checked calls to BAOPENW, WRYTE, GRIBCREATE, ADDGRID, ADDFIELD, and GRIBEND. The update ensures correct argument ranks and character declarations, removes the need for EXTERNAL, and preserves fully consistent behavior with NCEP library APIs.

Check list

• Branch is up to date with the authoritative repository (NOAA-EMC) develop branch.
• Checked the checklist for a developer submitting to develop.
• If a version number update is required, checked the updating version number checklist.
• If a new feature was added, a regression test for testing the new feature is added.

Testing

• How were these changes tested? Matrix
• Are the changes covered by regression tests? (If not, why? Do new tests need to be added?) Yes
• Have the matrix regression tests been run (if yes, please note HPC and compiler)? Hercules Intel and GNU
• Please indicate the expected changes in the regression test output, (Note the list of known non-identical tests.)
