When enabling Vulkan synchronization validation layers, I get at least 2 validation errors.
In a correct implementation, no synchronization errors occur in the most ideal case.

I think the issue is in RenderGraph::build_render_pass...
RenderGraph::build_render_pass
I believe this will go a way once use dynamic rendering in rendergraph2, so I am not sure if it's worth looking into this any further.
