We had some false positives where people would create their own types
that had interior mutability unrelated to hash/eq. This addition lets
you configure this as e.g. `arc-like-types=["bytes::Bytes"]`
In order to switch `clippy::uninlined_format_args` from pedantic to
style, all existing tests must not raise a warning. I did not want to
change the actual tests, so this is a relatively minor change that:
* add `#![allow(clippy::uninlined_format_args)]` where needed
* normalizes all allow/deny/warn attributes
* all allow attributes are grouped together
* sorted alphabetically
* the `clippy::*` attributes are listed separate from the other ones.
* deny and warn attributes are listed before the allowed ones

Improve "unknown field" error messages
Fixes#8806
Sample output:
```

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](481db40311/compiler/rustc_errors/src/emitter.rs (L1607)). So, hopefully, this is not a dealbreaker.

Add `await_holding_invalid_type` lint
changelog: [`await_holding_invalid_type`]
This lint allows users to create a denylist of types which are not allowed to be
held across await points. This is essentially a re-implementation of the
language-level [`must_not_suspend`
lint](https://github.com/rust-lang/rust/issues/83310). That lint has a lot of
work still to be done before it will reach Rust stable, and in the meantime
there are a lot of types which can trip up developers if they are used
improperly.
I originally implemented this specifically for `tracing::span::Entered`, until I discovered #8434 and read the commentary on that PR. Given this implementation is fully user configurable, doesn't tie clippy to any one particular crate, and introduces no additional dependencies, it seems more appropriate.
