This currently requires a CrOS image built with USE=vulkan and kernel 4.14 (needed for fence export).

The chrome side is easier, here's how to build with vulkan for Chrome OS eve:

cros chrome-sdk --board=eve
gn gen out_$SDK_BOARD/Release --args="$GN_ARGS enable_vulkan=true"
ninja -C out_$SDK_BOARD/Release -j1000 -k50 -l32 chrome chrome_sandbox

ozone_demo works but content will not work until viz can render without a VkSurfaceKHR.

ozone: drm: Inline vulkan_intel.h to fix build error

Including <vulkan/vulkan_intel.h> results in compilation errors when building
with the CrOS SDK, because we use vulkan.h from //third_party/vulkan.

This is a temporary issue since we're using a deprecated extension for
dmabuf import. Fix it by inlining the header.
