Move WIN32_LEAN_AND_MEAN and NOMINMAX into flags

They're literally always defined thusfar, and it's always possible to
include specific headers for other stuff. So, rather than litter the
source with defines (which might not even work in the likes of os.h if
some other system header already decided to define/include stuff), let's
just define it at the build script level.
