please, please, don't match on `Symbol::as_str`s, every time you do, somewhere in the world another waffle becomes sad...

Shouldn't this get a perf run? Removing symbols from the pre-interned list can impact performance. |

…r=compiler-errors Readd the matches_macro diag item This is now used by Clippy r? `@compiler-errors` This was removed in rust-lang#104383. But in the meantime Clippy now makes use of it https://github.com/rust-lang/rust-clippy/blob/dac600e32fce89cb4b05ae6edb0c47982b99eb48/clippy_lints/src/manual_is_ascii_check.rs#L153 --- This is blocking the Clippy sync. (kinda. I could work around it, but I don't want to play ping-pong with this change.)

As the title suggests, this removes unused symbols from
sym::and#[rustc_diagnostic_item]annotations that weren't mentioned anywhere.Originally I tried to use grep, to find symbols and item names that are never mentioned via
sym::name, however this produced a lot of false positives (?), for example clippy matching onSymbol::as_stror macros "implicitly" addingsym::. I ended up fixing all these false positives (?) by hand, but tbh I'm not sure if it was worth it...
