Run cargo fmt on the whole code base (#9394)

* Run cargo fmt on the whole code base

* Second run

* Add CI check

* Fix compilation

* More unnecessary braces

* Handle weights

* Use --all

* Use correct attributes...

* Fix UI tests

* AHHHHHHHHH

* 🤦

* Docs

* Fix compilation

* 🤷

* Please stop

* 🤦 x 2

* More

* make rustfmt.toml consistent with polkadot
