ext/mbstring: update to Unicode 15

Updates UCD to Unicode 15.1 (released 2023 Sept). The upcoming
Unicode 16 version will be released roughly on 2024 Sept.

Previously: 0fdffc18, #7502

UCD 15.1 `DerivedNormalizationProps` contains multiple properties in
the same line, which breaks the parser. This also updates the
`ucgendat.php` script to allow 2 or three fields in each line, and to
look for the `Cased` and `Case_Ignorable` properties in either of the
fields to mimic the previous behavior.
