They added some new scripts.
There were a few changes to the line break algorithm,
most notably there is more rules that require more context than before.
While not major, there was some shuffling and additions to our
implementation to match the new rules.
IDNA test data now disallows the trailing dot/empty root label,
technically to be toggled off by an option that controls a few things,
but we don't have options. For test-data they changed the format a
little - "" is used to mean empty string, while a blank segment is
null/no string, update the parser to read this.

emoji-data not being extracted in this branch

Add enumerator for the new Unicode version to QChar::UnicodeVersion.
Remap new line breaking classes to their Unicode 15.0 values:
* AK, AP and AS to AL,
* VI and VF to CM.
These are classes for new line breaking support for Indic scripts
that require more work.
Blacklist failing tests for now:
* tst_QUrlUts46::idnaTestV2
* tst_QTextBoundaryFinder::lineBoundariesDefault
* tst_QTextBoundaryFinder::graphemeBoundariesDefault
Regenerate the source files.

With this release 10 test cases in tst_qurluts46 were fixed, one
additional test case is failing in tst_qtextboundaryfinder and
is commented out. In total 62 line break test cases and 44 word
break test cases are failing.
A comment in src/corelib/text/qt_attribution.json was updated to
include the URL of the page containing UCD version number.

UAX #29 in Unicode 11 changed the EGC algorithm to its current form.
Although Qt has upgraded the Unicode tables all the way up to
Unicode 13, the algorithm has never been adapted; in other words,
it has been working by chance for years. Luckily, MOST
of the cases were dealt with correctly, but emoji handling
actually manages to break it.
This commit:
* Adds parsing of emoji-data.txt into the unicode table generator.
That is necessary to extract the Extended_Pictographic property,
which is used by the EGC algorithm.
* Regenerates the tables.
* Removes some obsoleted grapheme cluster break properties, and
adds the ones added in the meanwhile.
* Rewrites the EGC algorithm according to Unicode 13. This is
done by simplifying a lot the lookup table. Some rules (GB11,
GB12, GB13) can't be done by the table alone so some hand-rolled
code is necessary in that case.
* Thanks to these fixes, the complete upstream GraphemeBreakTest
now passes. Remove the "edited" version that ignored some rows
(because they were failing).
