landuse timeseries for 1979-2030 for ne120np4.pg3 resolution

[ekluzek]

CAM needs a landuse timeseries file for 1979-2030 for the ne120 resolution.

See the conversation here:

NCAR/amwg_dev#585 (reply in thread)

Definition of done:

• Add creation of it to the mksurfdata_esmf Makefile
• Create the dataset
• Add it to inputdata and rimport it
• Add it to namelist_defaults_ctsm

Since @adamrher is creating what's needed for short term tests, let's make this later, maybe even after we have CMIP7 datasets (ctsm5.4)?
