Rollup merge of rust-lang#144853 - Kivooeo:rust_-cleanup, r=Mark-Simulacrum

Remove unnecessary `rust_` prefixes

part of rust-lang#116005

Honestly, not sure if this can affect linking somehow, also I didn't touched things like `__rust_panic_cleanup` and `__rust_start_panic` which very likely will break something, so just small cleanup here

also didn't changed `rust_panic_without_hook` because it was renamed here rust-lang#144852

r? libs
