[HEAVY PERF] Optimize documentation lints 2/2
So, after https://github.com/rust-lang/rust-clippy/pull/14693 was merged, this is the continuation. It performs some optimizations on `Fragments::span` , makes it so we don't call it so much, and makes a 85.75% decrease (7.51% -> 10.07%) in execution samples of `source_span_for_markdown_range` and a 6.39% -> 0.88% for `core::StrSearcher::new`. Overall a 13.11% icount decrase on docs-heavy crates. Benchmarked mainly on `regex-1.10.5`. This means that currently our heaviest function is `rustc_middle::Interners::intern_ty`, even for documentation-heavy crates Co-authored-by: Roope Salmi <rpsalmi@gmail.com>
