pgsql: Move frontend-side archive APIs from src/common/ to src/fe_utils

Move frontend-side archive APIs from src/common/ to src/fe_utils/

fe_archive.c was compiled only for the frontend in src/common/, but as
it will never share anything with the backend, it makes most sense to
move this file to src/fe_utils/.
