more efficient recalculations from xlsx import of pivot tables
The import of pivot tables in xlsx triggers recalculations, even
though it's not necessary. Fixing that properly seems complex given
how ScDPObject is designed, so at least ensure the calculation is
efficient (formula grouping is otherwise done only after pivot
table import). This can especially noticeable for formulas where
groups make a big difference (e.g. COUNTIFS uses ScSortedRangeCache
only for formula groups).
