Do not try to load libraries natively under __WINE__

This was only half-implemented (e.g. OpenXR was still calling
GetModuleHandle), broke compilation with Vulkan due to mismatched ABI,
and wouldn't have worked anyways with winelib builds because we still
need access to wine's implementation of the Vulkan win32 winsys
integration. Perhaps this is still useful for dxvk-native but if so it
should be re-added under a DXVK_NATIVE flag.
