stdlib: map wchar_t to UInt16 on Windows

Browse Source 
This is an ABI breaking change for Windows.  `WCHAR` on Windows is
mapped to `short` (`-fshort-wchar` makes it `unsigned short`).  When C++
interop is enabled, `WCHAR` will be mapped to `wchar_t` which is then
mapped to `short` (or `unsigned short` if `-fshort-wchar` is specified).
Correct the mapping type to get the desired behaviour.
