#14079 Well Event: Export MSW keywords per well via explicit well list

Replace the include_welsegs / include_compsegs boolean flags on the
schedule-generation API with a list of wells (export_msw_for_wells) that
gates the multi-segment-well keywords. WSEGVALV and WSEGAICD are now gated
the same way as WELSEGS and COMPSEGS: all four are emitted only for wells
present in the list. An empty list (the default) suppresses MSW export for
all wells, while COMPDAT and well-control keywords are unaffected.

C++: RicScheduleDataGenerator takes a std::set<const RimWellPath*> mswWells
and generateMswForWell early-returns for wells not in the set.
RimcWellEventTimeline_generateSchedule replaces the two bool fields with a
scriptable PdmPtrArrayField<RimWellPath*>, resolved via
ptrReferencedObjectsByType().

Python: generate_schedule_text / generate_schedule expose
export_msw_for_wells (List[WellPath]) instead of the boolean flags. Updates
the well_event_schedule example and adds regression tests covering the
empty-list default, per-well selection, and WSEGVALV/WSEGAICD gating.
