Merge branch 'jonbob/cice/fix_ic_mode_usage' (PR #1297)

Add lost code to set variable based on ic_mode, for ICG compsets

This PR will add back some coding to set the mpas-cice
config_initial_condition_type based on the IC_MODE in build-namelist. This is
required for ICG compsets and was somehow lost.
