make CLDR radical-stroke order = UAX38

[markusicu]

Make the CLDR radical-stroke order of CJK ideographs match the order in UAX38 section 2.1.2 Sorting Algorithm Used by the Radical-Stroke Indexes.

For

• CLDR-17224 FractionalUCA.txt: review radical-stroke order / re: simplified radicals
• FractionalUCA.txt: change radical-stroke order to match UAX #38 #620

Changes:

• Change the 64-bit encoding of the sort order, moving the simplified-ness field below the number of residual strokes.
  • As a result, the traditional and simplified forms of characters are intermingled.
  • Therefore, any output by radical changes from multiple "buckets" like 182, 182', 182'' to a single "bucket" for radical 182.
  • Code-wise, many places that used to work with a radicalNumberAndSimplified now just work with the radicalNumber.
• Change the "extension" field from 1 bit which worked like in UTS10 Implicit Weights to a 4-bit field which, together with the code point, yields the same relative order as UAX38 block|code point.

Other code changes

• Some code worked with a 32-bit "short data" version of the 64-bit "order", by omitting some low-level fields and shifting down the high-level ones. I already had a TODO questioning the duplication. Now that I would have had to fiddle with the bit shifts & masks in two places, I switched the code to always work with the "long order".
• I had two parsers for the radical-and-simplified string. I created a shared function.
• There is a new TODO about more original-Unihan characters than before whose code point order differs from the CLDR, now UAX38, order. I am not planning to pursue this right now.

The modified output goes into CLDR:

• CLDR-17226 Unicode 16 final collation data cldr#3960

The full radical-stroke order is printed into the FractionalUCA.txt file there. (file format documentation)
See the CLDR PR for the diffs.

This change also affects some of the CLDR Chinese tailoring data.

It is unclear whether this change accommodates a second non-Chinese simplified radical, which is expressed using three apostrophes, and which is new for Unicode Version 16.0. See the Proposed Update of UAX #38.

It is unclear whether this change accommodates a second non-Chinese simplified radical, which is expressed using three apostrophes, and which is new for Unicode Version 16.0. See the Proposed Update of UAX #38.

I did that three months ago in one of the radical-and-simplified parsers:

• update CJKRadicals & EqUIdeo #803

The refactored parser here, at the end of RadicalStroke.java, handles up to three apostrophes, quoting the 16.0 proposed.html version of UAX38.

[markusicu]

PS: There is no character with a three-apostrophe radical as the primary kRSUnicode value. There are only two characters where such a radical is in the secondary value. This code only uses the primary value. That's why I had missed updating that version of the parser before -- it never saw a triple apostrophe.

[kenlunde]

Ah, good. For reference, draft code point U+3347B in the Extension J block (Unicode Version 17.0) will have 212'''.4 as its primary kRSUnicode property value.

[markusicu]

FYI: The output CLDR files are now in unicode-org/cldr#3960. I have updated the description of this PR here with a link for that as well.

[markusicu]

Could I get a review please? Or maybe a rubber stamp?
@macchiati?
@pedberg-icu approved the output in CLDR, maybe you could look at the generator changes here?
