Fix the crashdump() function in win32 when not compiled with UNICODE

`wsprintf` is an hybrid function (a macro) for
- either `char*` version `wsprintfA`
- either `wchar_t*` version `wsprintfW`

depending on `#define UNICODE` or not define UNICODE...

If we use `wsprintf`, then we must use the `TEXT` macro for passing the format literal, and declare filename as `TCHAR*` which also is a macro.<br>
https://docs.microsoft.com/en-us/windows/win32/intl/windows-data-types-for-strings

Here we explicitily use a `wchar_t*`filename and a `wchar_t*`literal format specification, so we want to bypass UNICODE macro and explicitely use `wsprintfW`
