Label opaque type for 'captures lifetime' error message

Providing more information may help make this somewhat opaque (lol) error message a bit clearer.

It's a pain to find otherwise.

Rustdoc search: Emit an error for unclosed generic

Now, search like `a<` will error as it should (and as written in the eBNF).

Use `Option::as_slice` where applicable

After rust-lang#105871 introduced `Option::as_slice`, this PR uses it within the compiler. I found it interesting that all cases where `as_slice` could be used were done with different code before; so it seems the new API also has the benefit of being "the obvious solution" where before there was a mix of options, none clearly better than the rest.

Match unmatched backticks in library/

Found with GNU grep:

```
grep -rEn '^(([^`]*`){2})*[^`]*`[^`]*$' library/ | rg -v '\s*[//]?.{1,2}```'
```

split out from rust-lang#108685 as per advice.
