From: Miguel Ojeda <ojeda@xxxxxxxxxx> commit 7d56786edcbdf58b6367fd7f01d5861214ad1c95 upstream. Some Clippy lints can be configured/tweaked. We will use these knobs to our advantage in later commits. This is done via a configuration file, `.clippy.toml` [1]. The file is currently unstable. This may be a problem in the future, but we can adapt as needed. In addition, we proposed adding Clippy to the Rust CI's RFL job [2], so we should be able to catch issues pre-merge. Thus introduce the file.
