Remove inline post code from ufs-weather-model public release branches

[climbfuji]

The inline post code in the UFS public release branches needs to be removed (together with the inline post stub code), otherwise we need to set the necessary preprocessor macros to use the stub code for all platforms.

Follow-up cleanup work:

• remove preprocessor macros for inline post stub code from platform configuration files
• remove NCEPlibs-post library build (just build the executable)

Following the discussion in #45, it was agreed to not remove the post code. Instead, we will add the -DNO_INLINE_POST option for all platforms (which compiles the stub inline post code that exits with an error if the inline post option is turned on), and remove the "module load" statements for the inline post NCEPlibs in ufs-weather-model.
