Vulkan: use one barrier to transit states for all subresources If a texture follow this rule: * old usages of all subresources are the same * new usages of all subresources are the same Then we can use one barrier to transit states for all subresources. We don't need to use one barrier per each subresource. This patch adds a flag at front-end to capture many (but not all) situations which follow the rule above, then we don't need to loop over every subresource at Vulkan backend.

Dawn provides several WebGPU building blocks:
