Ordering the descriptor sets by the change frequency on Vulkan, in increasing order (the opposite of D3D12 root signatures). The EDRAM binding never changes there (always one storage buffer), while the destination buffer binding may become changeable in the future (to split dispatches if exceeding `maxStorageBufferRange`, for example).
