Improve "unknown field" error messages
Fixes #8806
Sample output:
```
error: error reading Clippy's configuration file `/home/smoelius/github/smoelius/rust-clippy/clippy.toml`: unknown field `foobar`, expected one of

You can test this by (say) adding `foobar = 42` to Clippy's root `clippy.toml` file, and running `cargo run --bin cargo-clippy`.
Note that, to get the terminal width, this PR adds `termize` as a dependency to `cargo-clippy`. However, `termize` is also [how `rustc_errors` gets the terminal width](
