clients/simple-dmabuf-vulkan: New Vulkan client example

Browse source 
Example to serve as a reference of a basic Wayland client using
Vulkan with dmabuf. This does not use a traditional Vulkan swapchain
but implements it using imported gbm buffers. Also features use of
linux-explicit-synchronization-unstable-v1 with Vulkan.
Based on weston-simple-dmabuf-egl.
