For container build, revert 4 scripts once spack-stack is upgraded to 1.8.0

[DavidBurrows-NCO]

What is wrong?

When containerized build was added to gfs-utils, spack-stack 1.8.0 was used. For that reason, 4 files will need to be adjusted once gfs-utils upgrades to spack-stack 1.8.0.

1. replace and consolidate gfsutils_generic.lua with gfsutils_common.lua
2. remove gfsutils_generic.lua
3. in src/tave.fd/CMakeLists.txt, update lines 13-20 (if(LINK_W3EMC) to endif())
4. in src/vint.fd/CMakeLists.txt, update lines 13-20 (if(LINK_W3EMC) to endif())
5. CMakeLists.txt, remove option(LINK_W3EMC "Link w3emc library" ON)
