* Add support for building with ICU 75.1 or later
We use ICU via libxml2 implicitly. ICU 75.1 or later require C++17 for
its C++ API:
https://github.com/unicode-org/icu/releases/tag/release-75-1
> C++ code now requires C++17
But we use C++17. So `#include <libxml/xmlreader.h>` with ICU 75.1 or
later causes an error:

We don't need ICU C++ API. So we can avoid this error by disabling ICU
C++ API by defining `U_SHOW_CPLUSPLUS_API` as `0`.
