Windows: Define _WIN32_WINRT to 0x0600 (Vista)

Passed as a compiler define to be sure it is always define before windows.h
is loaded. This means that Godot officially requires Vista API or later, it will
not work on Windows XP or earlier.

Also fix a bogus check for Windows 7 API.

(cherry picked from commit 6323779596dea0db7f58afef7d3d3d5588ef20cb)
