Add partialeq_to_none lint
Initial implementation of #9275, adding lint `partialeq_to_none`. This is my first time working on `clippy`, so please review carefully.
I'm unsure especially about the `Sugg`, as it covers the entire `BinOp`, instead of just covering one of the sides and the operator (see the multi-line example). I was unsure if pinpointing the suggestion wouldn't be brittle...
changelog: [`PARTIALEQ_TO_NONE`]: Initial commit
`explicit_auto_deref` changes
fixes#9123fixes#9109fixes#9143fixes#9101
This avoid suggesting code which hits a rustc bug. Basically `&{x}` won't use auto-deref if the target type is `Sized`.
changelog: Don't suggest using auto deref for block expressions when the target type is `Sized`
changelog: Include the borrow in the suggestion for `explicit_auto_deref`
changelog: Don't lint `explicit_auto_deref` on `dyn Trait` return
changelog: Don't lint `explicit_auto_deref` when other adjustments are required
changelog: Lint `explicit_auto_deref` in implicit return positions for closures
Fix suggestions for `async` closures in redundant_closure_call
Fixes#9052
changelog: Fix suggestions given by [`redundant_closure_call`] for async closures
Move [`assertions_on_result_states`] to restriction
Close#9263
This lint causes regression on readability of code and log output. And printing runtime values is not particularly useful for majority of tests which should be reproducible.
changelog: Move [`assertions_on_result_states`] to restriction and don't lint it for unit type

unwrap_used: Don't recommend using `expect` when the `expect_used` lint is not allowed
Fixes#9222

Read and use deprecated configuration (as well as emitting a warning)
Original change written by `@flip1995` I've simply rebased to master and fixed up the formatting/tests. This change teaches the configuration parser which config key replaced a deprecated key and attempts to populate the latter from the former. If both keys are provided this fails with a duplicate key error (rather than attempting to guess which the user intended).
Currently this on affects `cyclomatic-complexity-threshold` -> `cognitive-complexity-threshold` but will also be used in #8974 to handle `blacklisted-names` -> `disallowed-names`.
```
changelog: deprecated configuration keys are still applied as if they were provided as their non-deprecated name.
