Allow ICU to use SortSupport on Windows with UTF-8

There is no reason to ever prevent the use of SortSupport on Windows
when ICU locales are used. We previously avoided SortSupport on Windows
with UTF-8 server encoding and a non C-locale due to restrictions in
Windows' libc functionality.

This is now considered to be a restriction in one platform's libc
collation provider, and not a more general platform restriction.
