Merge PR #2372 (Turn off MEGAN extension for non-benchmark sims)

This merge brings PR #2372 (urn off the MEGAN extension for fullchem "non-benchmark" simulations, by @yantosca) into the GEOS-Chem "no-diff-to-benchmark" development stream. This PR edits rundir scripts and HEMCO_Config.rc templates so that the MEGAN emissions are only activated for the fullchem_benchmark simulation. The other fullchem simulations use offline emissions (except when using GCAP2 met, which uses online MEGAN). Signed-off-by: Bob Yantosca <[email protected]>

 ### Changed
 - Now reset `State_Diag%SatDiagnCount` to zero in routine`History_Write` (instead of in `History_Netcdf_Write`)
+- Update rundir creation scripts to turn off the MEGAN extension for "standard" fullchem simulations
 
 ### Fixed
 - Typo in `setCommonRunSettings.sh` that made GCHP always choose mass fluxes for meteorology
