• Ready for review now, the commit messages in this PR are terrible so some editing of the commit message is required when we squash the commits on intake.
• Added all the generated weights files, I think this is the way to use them.
• There are a ton of clippy warnings from the weights converting from u64 to u64, they originate from the template file but this is subject to change again soon when 2D weights are introduced upstream.
• There are no change in test coverage as this is only a version upgrade
• There are two unrelated changes to weighs the system one is from running benchmarks and one is upstream chaining the weight system

Looks good to me. In my opinion, we should consider updating the weights template to remove the unnecessary cast that Clippy is complaining about, but that's for another time.
