    vulkan/renderpass: Use GENERAL for initial layout
    
    UNDEFINED initial layouts may not preserve the contents
    of the attachment after transitioning the layout. We want
    them to be preserved because we do partial rendering.
    
    Use GENERAL as the initial layout for render passes.
