Replace w3nco with w3emc.

[aerorahul]

Description

w3nco has been merged with w3emc and the latter is preferred going forward.
w3emc/2.9.1+ contains identical code as w3nco with the exception of gblevents.
This project does not depend on gblevents.

Solution

Replace dependency of w3nco with w3emc in the modulefile as well as in the build system.

Alternatives

None.

@kgerheiser, @Hang-Lei-NOAA, @aerorahul I got failure for replacing w3nco with w3emc/2.9.1 on Cray as:

My UPP working version is at /u/Wen.Meng/ptmp/develop/UPP on Surge. The build script is UPP/tests/compile_upp.sh.
I updated the following files:

        modified:   CMakeLists.txt
        modified:   modulefiles/wcoss_cray
        modified:   sorc/ncep_post.fd/CMakeLists.txt

Any suggestions on fixing? Thanks!

@WenMeng-NOAA this line needs to be changed to w3emc

UPP/CMakeLists.txt

Line 60 in 793ba3e

find_package(w3nco REQUIRED)

As well as this line

UPP/sorc/ncep_post.fd/CMakeLists.txt

Line 223 in 793ba3e

w3nco::w3nco_4

@kgerheiser I did change them. Somehow, it works on Dell, Hera, Orion but not Cray. It seems to me the configuration of NCEPLIBS on Cray is different from other platforms.

@kgerheiser @aerorahul My branch for replacing w3nco with w3emc/2.9.1 failed at "All checks" on github. It seems to me this online build function is loading w3emc/2.7. from /home/runner/w3emc-2.7.3. Any suggestions on the fix. Thanks!
