This will prevent anyone trying to use -co2_cycle with tropstrat_mam_oslo

Summary: Introduction of the ability to run with more complex atmospheric gas-phase chemistry.

Contributors: Dirk Olivié
Reviewers: Steve Goldhaber

Purpose of changes: ESCOMP#100 Add trop+strat chemistry scheme. The new scheme is a
combination of the aerosols from OSLO_AERO and the gas-phase species from the TS1 chemistry (pp_trop_strat_mam4_vbs).

Github PR URL: NorESMhub#149
Changes made to build system: None
Changes made to the namelist:

- The namelist used by the new compsets contains elements from the standard aerosol-only
NorESM namelist, but some external forcings have been removed as not used anymore
(ozone climatology, ozone climatology, volcanic stratospheric AOD).
- New things are : more emissions files are used, more GHGs/ODSs are prescribed, and the
lightning NOx scaling factor is now used.
- Concerning MEGAN fluxes from the land-model : more species are mapped into
monoterpene (to make it more in line with CESM).
- 3D-chemical species are taken into account in the radiation

Changes to the defaults for the boundary datasets:
- there are additional emission files
- some climatologies are not used anymore (ozone, oxidants)

Substantial timing or memory changes: an N1850_f19_tn14 simulation on 1024 CPUs is
much slower. The throughput is 8.67 simulated years/day (compared to 19.84 simulated
years/day in aerosol-only version)

aux_cam_noresm tests are BFB except for this new test
Turn off co2_cycle for tropstrat chemistry
Allow co2_cycle with stratospheric chemistry
