Introduce `NullValuePropertyMappingStrategy.CLEAR` for Maps and Collections (Iterables)

### Discussed in https://github.com/mapstruct/mapstruct/discussions/3381

This would be a continuation of #3387. In the implementation if `NullValuePropertyMappingStrategy.CLEAR` is used for `nullValuePropertyMapingStrategy` then we should provide a compile error, since the strategy does not make sense for non iterable / map types.
