[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] I am cleaning the Win32 security plugin unicode mess. (2a6304d)

Unfortunately, this ain't gonna work, because dwSize is the size of the buffer in bytes, not the size in character (WCHAR)

This is because RegQueryValueEx is very low level and can read several types, thus handle the buffer as un-interpreted bytes.
Therefore, dwSize must be multiplied by sizeof(WCHAR) before the call, and divided by sizeof(WCHAR) after the call if we use the RegExQueryValueW variant, so as to express the size in characters like we intend to.
