Bug #19007: Unicode tables differences from Unicode.org 14.0 data

----------------------------------------
I found the header in Unicode Emoji 14.0 data files had changed slightly (and again at 15.0), but `enc/unicode/case-folding.rb` didn't follow it.
Then I fixed it and rebuilt the headers under `enc/unicode/14.0.0`, `name2ctype.h` had diffences from the master, as bellow.

`CR_Lower`, `CR_Cased` and `CR_Other_Lowercase` just seem misses in the previous operation, and no problems.

But U+11720..U+11721 in `CR_Grapheme_Cluster_Break_SpacingMark` is absent in the original data of the Unicode.org.
According to @naruse's investigation, it was removed at the commit [Update to Unicode 14.0.0], while U+11720 is still SpacingMark in the latest https://www.unicode.org/reports/tr29/.

[Update to Unicode 14.0.0]: https://github.com/latex3/unicode-data/commit/5570040ac8a30e2c2ca4912d415eca...
