    wayland/vulkancontext: Sync surface state before vkQueuePresentKHR
    
    A side effect of vkQueuePresentKHR is the Vulkan implementation calling
    wl_surface_commit() on the corresponding Wayland surface. Thus, before
    this, we must synchronize the surface state (e.g. opaque region, window
    geometry, etc) that changed since last time. Prior to this commit this
    was done after calling vkQueuePresentKHR(), causing the surface state to
    always correspond to the previous buffer state. As of this commit this
    is now done before calling vkQueuePresentKHR(), thus before
    wl_surface_commit().
