[#10047](https://github.com/rust-lang/rust-clippy/pull/10047)
add `suppress_restriction_lint_in_const` config
According to #9808 , add a new lint `suppress_lint_in_const` to report even in const context. BTW, i am not good at naming either, if anyone have a better idea, i am happy to change it.
This PR is still in progress, so i keep it draft.
- \[x] Followed [lint naming conventions][lint_naming]

- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`

Fix 10021
This PR proposes a fix for #10021.
The problem is similar to the one that `@mikerite` described in #9505. The compiler is generating an empty substitution for a call, even though the type of `Self` seems to be needed for a predicate. In `@mikerite's` case, the call was to [`IntoFuture::into_future`](https://doc.rust-lang.org/std/future/trait.IntoFuture.html#tymethod.into_future). In this case, the call is to [`Try::branch`](https://doc.rust-lang.org/std/ops/trait.Try.html#tymethod.branch).
The proposed fix is to verify that the parameter whose type is changing has an index within the substitution. The strikes me as a reasonable approach, since if the check were to fail, the following code would be a no-op:
4c123a06ba/clippy_lints/src/methods/unnecessary_to_owned.rs (L420-L428)
Like `@mikerite's` original solution, this solution turns ICEs into false negatives.

Fix#9958
This PR fixes#9958. In order to fix the issue, the lint will now peel reference operators and enclose the expression with parentheses when necessary.

Don't lint `from_over_into` for opaque types
fixes#9935
This is stalled until the next sync. The impl in question can't be written on the pinned nightly.

Move `unnecessary_unsafety_doc` to `pedantic`
This lint was added in #9822. I like the idea, but also agree with #9986 as well. I think it should at least not be warn-by-default. This is one of these cases, where I'd like a group between pedantic and restriction. But I believe that users using `#![warn(clippy::pedantic)]` will know how to enable the lint if they disagree with it.

Since the lint is new:
changelog: none
r? `@flip1995` since I'd suggest back porting this, the original PR was merged 16 days ago.
Closes: #9986 (While it doesn't address everything, I believe that this is the best compromise)
