zink: Fix building on macOS

This fixes building on macOS:
  Disable ZINK_USE_DMABUF on macOS, it is unsupported.
  Import vk_mvk_moltenvk.h for MVK_VERSION in zink_resource.c.
  Add additional build arguments (see meson.build) to build properly.

To build on macOS, you will probably need to run:
  brew install bison llvm cmake libxext xquartz ninja xorgproto meson

And you also need to setup meson with something like:
  -Dmoltenvk-dir=/Users/<Username>/VulkanSDK/<VersionNumber>/MoltenVK
  -Dc_std=c11
