Resolves: tdf#123714 tdf#123736 all split formula groups; tdf#120013 related

Add all split shared formula groups to regrouping and mark for
listening, even if the references had not be to adjusted.

This partly also resolves tdf#120013 but there's more to that, a
remaining partial group is not updated.

Listening when grouping in ScColumn::AttachNewFormulaCells(), (tdf#123736)

Not directly related to tdf#123736 but similar approach.
Setting a vector with ScColumn::SetFormulaCells() is currently
only done for Undo documents, but implementation provided
listening as only single cell listening for not-undo/clip
documents, which wouldn't work if actually used in grouping
context. The upcoming unit tests will use SetFormulaCells() for
checks.
