Update to Unicode 15.0.0

[Bruno Haible]

With these two patches, the Unicode support is updated to Unicode 15.0.0.

The first patch makes it possible again to compile gen-uni-tables.c
with the usual tools (GCC 11) on my usual dev environment. I don't like
to be forced to use a compiler such as gcc-experimental or clang 15
in order to compile gen-uni-tables.c.

The second patch is the update proper.

        gen-uni-tables: Temporarily revert last change.
        * lib/gen-uni-tables.c: Include <stdbool.h>, unless the C compiler
        advertises compliance to ISO C 23.
