Request memory with VK_MEMORY_PROPERTY_HOST_COHERENT_BIT enabled for model staging buffers.

Browse source 
There is no guarantee in the spec on the order of the following memory types:
                VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT | VK_MEMORY_PROPERTY_HOST_CACHED_BIT,
                VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT | VK_MEMORY_PROPERTY_HOST_COHERENT_BIT,
    which means we can't assume that the first memory type with VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT is going to be coherent.
