Unify GeosCore module initializations to accept the same arguments

[jimmielin]

This commit unifies all modules in GeosCore to accept the same set of arguments - (am_I_Root, Input_Opt, State_Chm, State_Diag, RC)

This is done in preparation for moving USE-associated arrays that are dependent on grid sizing (i.e. (IIPAR, JJPAR, LLPAR)) in these modules
to State_Chm, permitting multi-domain GC-WRF coupling and, in a broader sense, running simultaneous instances of GEOS-Chem modules in the same CPU.

Important Note: GCHP Code Update Necessary
This commit changes the entry point for Init_TOMS which is being called in GCHP by gigc_chunk_mod.F90, breaking compilation for GCHP.

Solution: That entry point should be removed - please refer to the following code context taken from gigc_chunk_mod, around lines 305:

    ! Initialize other GEOS-Chem modules
    CALL GC_Init_Extra( am_I_Root, HistoryConfig%DiagList, Input_Opt,    &
                        State_Chm, State_Diag, RC ) 
    ASSERT_(RC==GC_SUCCESS)

    ! ...

    ! Allocate array of overhead O3 columns for TOMS if chemistry is on
    IF ( Input_Opt%LCHEM ) THEN
       CALL Init_TOMS( am_I_Root, Input_Opt, RC )
       ASSERT_(RC==GC_SUCCESS)
    ENDIF

Within GC_Init_Extra (from GC_Environment_Mod), the following already exists:

    !-----------------------------------------------------------------
    ! Initialize "toms_mod.F"
    !-----------------------------------------------------------------
    CALL Init_Toms( am_I_Root, Input_Opt, State_Chm, State_Diag, RC )
    IF ( RC /= GC_SUCCESS ) THEN
       ErrMsg = 'Error encountered in "Init_Toms"!'
       CALL GC_Error( ErrMsg, RC, ThisLoc )
       RETURN
    ENDIF

Which runs independent of Input_Opt%LCHEM selection. Therefore I believe that in the GCHP source, the Init_TOMS code is redundant and should be removed. It does not throw a duplicate allocation error, because there are ALLOCATED sanity checks within Init_TOMS code.
