format Cargo.toml aswell

[dvc94ch]

inconsistent formatting of Cargo.toml files is annoying. there are some tools to format toml files, but might make sense to have support in rustfmt so that cargo fmt and rust-analyzer can format Cargo.toml files too. I guess there could even be more sophisticated support in the future, like autocompletion of feature names defined in Cargo.toml. But if it just supported formatting Cargo.toml's I'd be very pleased.
