Define Windows header macros only once in CMakeLists.txt

Instead of defining the macro `WIN32_LEAN_AND_MEAN` and sometimes also the macro `_WIN32_WINNT` in each file that directly or indirectly includes `<windows.h>`, only define these macros once consistently in `CMakeLists.txt`.

Also define `NTDDI_VERSION`, which is the new macro to specify the minimum Windows version starting with Windows Vista. This macro needs to be defined in addition to old `_WIN32_WINNT` macro, according to the documentation.
