[Feature]: Removal of CDAT, cdms, cdutil, etc.

[lee1043]

Remove dependency to CDAT libraries.

Note: This task is aligned with E3SM Unified Env version update. See E3SM-Project/e3sm-unified#118

During the mean time, numpy version restriction caused by cdms was resolved by @xylar. The patched cdms can be installed via the following way:

E3SM-Project/e3sm-unified#118 (comment)

We can make the removal as two steps:

1. update numpy to newer version to ensure no breaking
2. remove cdat dependencies

Note: remaining cdat components are in:

• ENSO
• Monsoon Wang
• precip distribution
• diurnal cycle

Make sure to test cdms2 and numpy >=2.0, because it's definitely possible that my patching hasn't caught all the incompatibilities. Please ping me as you notice numpy issues and/or create an issue: https://github.com/conda-forge/cdms2-feedstock/issues
