Subject: [PATCH] Fix building `LibcShims.cpp` with MSVC v14.37

`_swift_stdlib_configure_console_mode` reverts console codepage on Windows using `atexit`, which is declared in `stdlib.h`.

Add the missing `#include <stdlib.h>` to unblock building Swift `stdlib` with MSVC v14.37 (Visual Studio 17.7).
