This should make Clippy more resilient and will unblock #78343.
This PR is made against rust-lang/rust to avoid the need for a subtree
sync at @flip1995's suggestion in rust-lang/rust-clippy#6310.
Add a case to `lint_search_is_some` to handle searching strings
Fixes: #6010
This adds a lint which recommends using `contains()` instead of `find()` followed by `is_some()` on strings as suggested in #6010.
This was added as an additional case to
5af88e3c2d/clippy_lints/src/methods/mod.rs (L3037)
I would really appreciate any comments/suggestions for my code!

add error_occured field to ConstQualifs,
fix#76064
I wasn't sure what `in_return_place` actually did and not sure why it returns `ConstQualifs` while it's sibling functions return `bool`. So I tried to make as minimal changes to the structure as possible. Please point out whether I have to refactor it or not.

Remove `allow` in `option_option` lint test
As it is not triggering locally anymore, I propose to remove `#[allow(clippy::option_option)]` from the test.
The goal is also to see what happens on CI.

Add `let_underscore_drop`
This line generalizes `let_underscore_lock` (#5101) to warn about any initializer expression that implements `Drop`.
So, for example, the following would generate a warning:
```rust
struct Droppable;
impl Drop for Droppable {
fn drop(&mut self) {}
}
let _ = Droppable;
```
I tried to preserve the original `let_underscore_lock` functionality in the sense that the warning generated for
```rust
let _ = mutex.lock();
```
should be unchanged.
*Please keep the line below*
