Since ubrk_clone is draft status, we need to hide U_HIDE_DRAFT_API definition to use it. So I suggest,

1. Let's create a new cpp/h files, IntlWorkaround.h IntlWorkaround.cpp
2. Annotate @no-unify to IntlWorkaround.cpp since we want to avoid including unicode/ubrk.h without removing U_HIDE_DRAFT_API
3. Define a wrapper function around ubrk_clone / ubrk_safeClone in IntlWorkaround.cpp. To use draft ICU APIs, we need some special handling. Please check IntlListFormat.cpp for example :)
