Remove unused namelist variables

[billsacks]

Description of changes

Remove some unused namelist variables: glc_nx, glc_ny, and some glc2lnd and lnd2glc mapping file variables.

In addition to doing some general cleanup, the motivation for removing these is because they will be hard to support with the upcoming capability to have multiple GLC grids.

Testing performed if application target is CESM:(either UFS-S2S or CESM testing is required):

• (recommended) CIME_DRIVER=nuopc scripts_regression_tests.py
  • machines: cheyenne
  • details (e.g. failed tests):
    • Testing run in the context of cesm2_3_beta03
    • Two tests failed; these also fail from out-of-the-box cesm2_3_beta03:
      • test_j_createnewcase_user_compset_vs_alias
      • ERIO_Ln11.f09_g16.X.cheyenne_intel from test_full_system
• (recommended) CESM testlist_drv.xml
  • machines and compilers: cheyenne; all compilers for which tests are defined
  • details (e.g. failed tests):
    • Ran tests in xml category nuopc; did not perform baseline comparisons
    • Three tests failed; I'm pretty sure these are due to pre-existing issues:
      • ERR_Vnuopc_Ld5.f09_t061.B1850MOM.cheyenne_intel.allactive-nuopc_cap_io & ERS_Vnuopc_Ld5.f19_g17.B1850.cheyenne_intel.allactive-nuopc_cap_io: can't find nuopc_cap_io testmods dir
      • ERS_Vnuopc_Lm13.f10_f10_mg37.I1850Clm50SpG.cheyenne_intel: Can't do restart run with CISM & NUOPC currently
• (optional) CESM prealpha test
  • machines and compilers
  • details (e.g. failed tests):
• (other) please described in detail: CISM's aux_glc test suite
  • machines and compilers: cheyenne intel & gnu
  • details (e.g. failed tests):
    • Tests run in the context of cismwrap_2_1_85
    • All tests pass and are bit-for-bit with baselines; NLCOMP failures as expected

Testing performed if application target is UFS-coupled:
