Better handle interaction with outer attributes when `;` is missing.

Fix some confusing wording and improve slice-search-related docs

This adds more links between `contains` and `binary_search` because I do think they have some relevant connections. If your (big) slice happens to be sorted and you know it, surely you should be using `[3; 100].binary_search(&5).is_ok()` over `[3; 100].contains(&5)`?
This also fixes the confusing "searches this sorted X" wording which just sounds really weird because it doesn't know whether it's actually sorted. It should be but it may not be. The new wording should make it clearer that you will probably want to sort it and in the same sentence it also mentions the related function `contains`.
Similarly, this mentions `binary_search` on `contains`' docs.
This also fixes some other minor stuff and inconsistencies.

Suggest calling method on nested field when struct is missing method

Similar to the suggestion to change `x.field` to `x.nested.field`, implement a similar suggestion for when `x.method()` should be replaced with `x.nested.method()`.

delay bug when adjusting `NeverToAny` twice during diagnostic code

Addresses Issue 96335 (rust-lang#96335) by using `delay_span_bug` instead of an assert and returning an error type from `check_expr_meets_expectation_or_error`.

Fixes rust-lang#96335
