Can I remove the CPL_CVSID macro?

[schwehr]

Feature description

Any objections to me removing the CPL_CVSID() macro? It's no longer present in any source files? Are there any uses of GDAL that count on CPL_CVSID being present?

Happy to make a PR, but want to check first.

Looking at https://codesearch.debian.net/search?q=CPL_CVSID and confirming with https://github.com/search?q=repo%3AOSGeo%2Fgdal-grass%20CPL_CVSID&type=code, OSGeo/gdal-grass is a known user of the macro (hopefully the only one... ?) . So a preliminary step would be to remove its use from there, wait for an official release of OSGeo/gdal-grass, and then remove it here
