win32: fix some Clang warnings

- win32-console-wrapper.c was inconsistently using the explicit Unicode
  versions of some Windows API functions and structures.
- vo.c should use llabs for int64_t, since long is 32-bit on Windows.
- vo_direct3d.c had a potential use of an uninitialized variable if it
  took the first goto error_exit.
