[PATCH] Avoid redefinition of UTF8_STRING

[Owen Smith <owen.smith@xxxxxxxxxx>]

UTF8_STRING is defined by MSVC 14.23 (_MSC_VER 1923, VisualStudio 16.3)
Use preprocessor to only define UTF8_STRING on earlier compiler
versions. This allows XenIface to build with both EWDK 19h1 18362.84 and
EWDK vb_release 19041.1
