Auto merge of #137612 - Kobzol:bootstrap-2024, r=onur-ozkan

Update bootstrap to edition 2024

The stage0 compiler now supports edition 2024, so we can update bootstrap to it. I manually reviewed all the changes from `cargo fix --edition` and reverted most of them (`if let` -> `matches` changes and two unneeded usages of `use <>`).
