Source: Fix typo in _WIN32 preprocessor checks

Since CMake's default compiler flags with MSVC include `-DWIN32` for
historical reasons, a few preprocessor conditions were accidentally
checking for `WIN32` instead of `_WIN32`.  The corresponding blocks
were left out when compiling official binaries for `cmake.org` because
we hard-code compiler flags without `-DWIN32`.

Fixes: #22764
