I18n: disambiguate and extract a few messages

Disambiguate:
- Lower / Upper (case)
- Spray (ocean modifier)
- Keep Original (clip, grease pencil, object)
- Screen [space] (inside some enum items, mostly)
- Cast Shadow ("shadow that is cast", not "to cast a shadow")

Extract:
- Line Art Light Reference Near and Far
- Mesh vertex attribute domain: Vertex
