Dylan M. Taylor b21a8541e7 Row auto-fit: sweep merges once per sheet instead of per row (#3195) ...

* Row auto-fit: sweep merges once per sheet instead of per row

auto_row_height() picked the merges touching a row by scanning every
merge on the sheet, and opening a workbook (fit_imported_rows) or a
commit fitting many rows called it per row, so rows x merges
comparisons ran synchronously on open.

Rows are fitted in ascending order, so a MergeSweep sorts the sheet's
merges by first row once and keeps only those active on the current
row. All comparisons count against MERGE_FIT_WORK (50,000,000) per
pass; past it the remaining rows keep the heights they have.
auto_row_height keeps its signature for single rows.

* address review: share the merge-comparison budget across the whole auto-fit pass

* address review: build the merge sweep lazily, after the row fast paths

* address review: charge the merge sort to the fit budget, keep row heights once it is spent

* address review: a pass that fits one row scans the merges instead of sorting them
