[patch] Correct Win32 projects to link with the correct ICU libraries

The various combinations of "ICU Release"|"ICU Debug" and Win32|x64 were mostly incorrect, either using a release library where a debug library was needed, or just plain not linking with any ICU library at all.

The attached patch rectifies these problems for all VC versions. It's been specifically tested on our CI systems for VC12 and VC14, but the change is identical for all older versions.
