Fix: Building with WITH_OPENVDB=OFF and WITH_LZMA=ON

This caused NOMINMAX not to be defined when `LzmaLib.h` includes
`windows.h` which causes a definition of min which upsets `std::min`

By moving BLI_winstuff.hh up, it will take care of this define for
us in case it was not yet defined regardless of openvdb being on or
off
