RFR: 8268927: Windows: link error: unresolved external symbol "int __cdecl convert_to_unicode(char const *, wchar_t * *)"

[David Holmes]

Please review this trivial fix to add a missing "static" to a function prototype. For some reason VS 16.9.3+ doesn't treat this as an error but earlier versions do (and gcc/g++ confirms).

Tested our CI builds remain okay with this change.

Thanks,
David
