Use MAPL_UNDEF value for HEMCO missing values if using GCHP or GEOS

[lizziel]

This PR is 1 of 2 for GCHP super-project. See instructions here:
geoschem/GCHP#258

The update in this pull request includes the following:

1. Change the definition of missing value parameter HCO_MISSVAL when using GCHP or GEOS to match the missing value definition used in MAPL (1e15 stored in MAPL parameter MAPL_UNDEF).
2. Introduce pre-processor switch MAPL_ESMF for use in GCHP and GEOS.
3. Remove "temporary" kludge from 2017 that identified missing mask values as >1e14 if using GCHP.

These updates are necessary following a MAPL update to flag missing values by comparing input values to the netCDF file _FillValue attribute. MAPL now assigns MAPL_UNDEF to missing values and skips the cells during regridding. With this PR the missing values will later be recognized and properly handled in HEMCO during masking and scaling.

This pull request must be merged as the same time as MAPL PR geoschem/MAPL#21

This PR, coupled with the MAPL PR, will cause minor differences in the GCHP benchmark simulation due to a change in EDGAR diurnal scale factors used for CEDS NO. Previously MAPL did not flag missing values in the file and used _FillValue 1.0 as valid data. Using 1.0 instead of missing values in the regridding effectively dilutes valid scale factor data. This will be seen as differences along the coast in the GCHP benchmark.
