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).

Too much of the existing code in Qt requires eager evaluation without
large scale modifications. Combined with the fact that supporting both
eager and lazy evaluation has a high maintenance burden, keeping lazy
evaluation, at least in its current state, is not worth it.
This does not diminish other benefits of the new property system, which
include
- a C++ API to setup and modify bindings and
- faster execution compared to QML's existing bindings and the ability
to use them without having a QML engine.
We do no longer benefit from doing less work thanks to laziness. A later
commit will introduce grouping support to recapture some of this
benefit.

eager evaluation now when a dependency in a binding changes.
