Utilities/Release: Create a Windows 64-bit binary
Compile with `-D_WIN32_WINNT=0x502` to use a WinXP-compatible API. Compile with `-D_USING_V110_SDK71_` to tell the VS standard library headers that we are building with a WinXP-compatible Windows SDK. Link executables with `-subsystem:console,5.02` to make them runnable on Windows XP 64-bit. Ideally `cmake-gui` should instead be linked with `-subsystem:windows,5.02` but with the Ninja and Makefile generators CMake adds `-subsystem:windows` after our `-subsystem:console,5.02` flag and the linker seems to interpret this combination as we need.
