This numeral indicates the "minimum system required" to run the resulting
program. Dolphin targets Vista+, so it should be 0x0600. However in practice,
_WIN32_WINNT just removes up-level API declarations from headers. This is a
problem for XAudio2 and XInput, where Dolphin expects to compile against the
Win8+ versions of their headers. So while we really need Vista+ level of
support, we declare Win8+ here globally. If this becomes a problem, the
higher declaration can be contained to just the XAudio2/XInput related code.
