* M12.AR7: sort Arabic text by its letters, not its vowel marks or digit script
* M12.AR7: order marked Arabic text the way Excel does
Checked compare_text against Excel 16.0 build 20527 (en-US) via COM:
Range.Sort, =SORT() and the < / = operators over ~300 strings. Fixes the
mismatches inside this change's scope:
- The tie-break compared raw code points, so an RLM-prefixed word sorted
after every vowelled form of it, "12" after "١٢", and a tatweel
form after a shadda form. Ignorable characters are now skipped at the
tie-break too.
- Marks are compared letter by letter (an unmarked letter first), so a
mark on an earlier letter outranks the digit or letter after it, as in
Excel ("ب١" < "بَ1", "بپ" < "بَپ").
- Marks rank in Excel's measured order (sukun before shadda), and the
Quranic marks Excel skips (U+0610–061A, U+06D8–06ED except 06DD/06DE/
06DF/06E0/06E5/06E6/06E9) are skipped by letter order.
- Excel also ignores bidi embeddings/overrides/isolates, BOM, soft hyphen,
CGJ and word joiner; they now are ignored too (ZWSP is not, as in Excel).
Equality is unchanged. Regression tests use the orders Excel produced.

A source that takes in the cell being checked (=$A1:$A2 on A2:A3 is A2:A3 at A3) listed the value being typed, so any new value passed. The list is now read from the workbook as it was before the entry, as in Excel.
A list source such as =$B1:$B2 is written for the rule's top-left cell.
list_items evaluated it there for every cell, so the dropdown and the
check showed and accepted the top-left cell's items everywhere. It now
takes the cell and shifts the source to it, as Excel does.
