winevulkan: Explicitly define VK_NULL_HANDLE.

This fixes a mismatch that occurred when the default type of VK_NULL_HANDLE and
VK_DEFINE_NON_DISPATCHABLE_HANDLE had changed in the upstream XML. Because WineVulkan overrides the
definition of VK_DEFINE_NON_DISPATCHABLE_HANDLE we must do the same for VK_NULL_HANDLE so that the
types match.
