Auto merge of #139588 - Kobzol:rust-analyzer-opt, r=jieyouxu
Use LTO to optimize Rust tools (cargo, miri, rustfmt, clippy, Rust Analyzer)
Trying if LTO/PGO can help RA's performance, and by how much. As `@Noratrieb` suggested, we could actually LTO optimize all the important tools.
CC `@Veykril` I realized that we don't even do LTO for Rust Analyzer, that could be a very low hanging fruit to improve its performance 😅
