Bug fix for chem_opt=100 (vbs_het), racm_soa_vbs_het_kpp initialization

[SeregaOsipov]

TYPE:bug fix

KEYWORDS: racm_soa_vbs_het_kpp, aerosols

SOURCE: Sergey Osipov (KAUST)

DESCRIPTION OF CHANGES: Problem: The bug was introduced after splitting chem_opt 100 and 106. Currently, the chemistry initialization always calls for module_aerosol_soa_vbs routine, leaving the module_aerosol_soa_vbs_HET and corresponding data constants unitialized. As a result, aerosol concentrations are set to 0 after the first time integration (10**-16).

To verify the bug fix, initialize WRF-Chem with non-trivial IC and save the next time step into nc. Check that values are non-trivial (e.g., so4aj, soila).

Solution: Differentiate between module_aerosol_soa_vbs and module_aerosol_soa_vbs_het initialization routines

@jordanschnell This one requires approval again because of the base branch change.
