Let EnsoMultiValue.to_text delegate to first type to_text

[JaroslavTulach]

Based on to_text discussion, but overall question is: what should EnsoMultiValue do with Any methods? If we delegate to_text to the first type, then we should probably delegate all of them. @radeusgd originally wrote:

IMO to_text of first type is best. It does hide the 'other values' and that is not ideal, but given the kind of use cases we want to use multi-values for (e.g. the Column & Integer_Column), I think that delegating to the first type is the best we can do to keep this sensible.

In that regard, perhaps to_text shouldn't be any different than e.g. to_js_object or to_defautl_visualization_data that we use to visualize the values. These will also delegate to the first value.

As a side note: Any.to should probably use EnsoMultiValue as self: #11897 (comment)

Update on Jan 24, 2025: Another example where EnsoMultiValue should be send as self is here https://github.com/enso-org/enso/pull/12120/files#r1928099736 - again needed for dispatch of Any instance methods.

Indeed it would be good if methods like catch or throw_on_warning did not lose the intersection types. It is not intuitive that they would be lost (I understand why it happens but writing the code it is not an intuitive behaviour) - it requires the user to think hard whether their code may be getting an intersection type and do workarounds to avoid losing it. That is definitely not desirable - I think the intersection types should be as transparent as possible.
