Bernd Kuhls 7d4e403f02 package/xerces: fix build with recent versions of ICU ...

Since Buildroot commit dcee99507c in
2025.11-rc1 that bumped package/icu to version 77-1, the build of xerces
with ICU support enabled fails:

In file included from /home/bernd/buildroot/output/host/i586-buildroot-linux-gnu/sysroot/usr/include/unicode/uset.h:38,
                 from /home/bernd/buildroot/output/build/xerces-3.3.0/src/xercesc/util/regx/RangeToken.cpp:40:
/home/bernd/buildroot/output/host/i586-buildroot-linux-gnu/sysroot/usr/include/unicode/char16ptr.h:271:55:
 error: 'is_same_v' is not a member of 'std'; did you mean 'is_same'?

Indeed, ICU now requires C++17. Instead of using a patch from Gentoo[1]
we use a backported upstream commit, limited to CMakeLists.txt, to raise
the c++ version.

The build error was not recorded yet by the autobuilders but can be
reproduced with this defconfig:

BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_XERCES=y
BR2_PACKAGE_ICU=y
