Updates the databease to the Unicode release 16.0.0. The algorithms of the Grapheme clustering rules have not changed.
Contains various Unicode data files used in the library for Unicode support
To update all files to the last published Unicode version issue the following
command in the directory containing this file.
wget \
https://www.unicode.org/Public/UCD/latest/ucd/DerivedCoreProperties.txt \
https://www.unicode.org/Public/UCD/latest/ucd/auxiliary/GraphemeBreakProperty.txt \
https://www.unicode.org/Public/UCD/latest/ucd/auxiliary/GraphemeBreakTest.txt \
https://www.unicode.org/Public/UCD/latest/ucd/emoji/emoji-data.txt \
https://www.unicode.org/Public/UCD/latest/ucd/extracted/DerivedGeneralCategory.txt \
https://www.unicode.org/Public/UCD/latest/ucd/EastAsianWidth.txt
Afterwards build the `libcxx-generate-files` target to update the generated
Unicode files.
