optimize expensive EndListener() calls (tdf#102364)

The document has a large (1M cells) column, and when replacing old cells
with new cells during undo as described in the bugreport the repeated
calls to EndListener() from ScColumn::DetachFormulaCell() get quite costly.
Optimize this by doing a single EndListeningFormulaCells() call.
