Rollup merge of #126452 - compiler-errors:raw-lifetimes, r=spastorino

matthiaskrgr · web-flow · commit a9bf2ca7aeb8 · 2024-09-07T23:30:10.000+02:00
Implement raw lifetimes and labels (`'r#ident`)

This PR does two things:
1. Reserve lifetime prefixes, e.g. `'prefix#lt` in edition 2021.
2. Implements raw lifetimes, e.g. `'r#async` in edition 2021.

This PR additionally extends the `keyword_idents_2024` lint to also check lifetimes.
