windows: support ill-formed UTF-16 in UTF16PtrToString

Browse Source 
UTF16PtrToString does not support ill-formed UTF-16 because it uses
utf16.Decode, which expects well-formed UTF-16.

This CL updates the UTF16PtrToString implementation to use
UTF16ToString instead of utf16.Decode, which supports ill-formed
UTF-16 since go1.21 via syscall.UTF16ToString.
