After thinking about this some more, I have committed a change to define
HAVE_UCOL_STRCOLLUTF8 on Windows unconditionally. Until someone figures
out a different way, I think it's better that users of newish versions
of ICU get the newer/better behavior, and users of older versions can
file a bug. The alternative is that we forget about this and we keep
using the old code path indefinitely.
