#14684 Simulator Events: Allow schedule generation without a grid case

Grid-dependent keywords (WELSPECS, COMPORD, COMPDAT, COMPLUMP, WELSEGS, COMPSEGS, WSEGVALV, WSEGAICD) are skipped and reported as WARNING comments in the schedule header, so production-data-only setups can still generate DATES and well control keywords.
