kMaxBindingsPerGroup is not a real WebGPU limit. Code in Dawn that
uses it now uses dynamically sized vectors, optimistic stack_vecs or
a different limit like kMaxDynamicBuffersPerPipelineLayout.
The CL introduces kMaxOptimalBindingsPerGroup=32 which is used to size
the static portion of stack_vecs, but the value is tentative.
