New advertise/realize implementation in datm

[mvertens]

This PR demonstrates a new advertise/realize implementation that is totally self contained within datm
and no longer depends on shr_nuopc_fldlist data types.
It also eliminates all calls to seq_timemgr_mod from datm_comp_mod and atm_comp_nuopc.
These type of changes will be implemented in future PRs to the other CIME data models.

Test suite: ran the following tests and verified that they did not change answers relative to the head of nuopc_cmeps

ERS_Vnuopc_Ln5.f45_f45_mg37.I2000Clm50SpNuopc.hobart_intel
ERS_Vnuopc_Ln10.T62_g16.CMOM.hobart_intel
Used mvertens/app_cesm-cmeps UFSCOMP branch to carry this out

I traced the issue to needing to remove the first EClock parameter in calls to datm_comp_init() and datm_comp_run() in cime/src/components/data_comps/datm/mct/atm_comp_mct.F90. I restarted the test on Cheyenne. If they pass we'll leave this PR closed and I will push the fix directly to nuopc-cmeps.
