Rollup merge of #157888 - TaKO8Ki:fix-raw-ref-nested-call-arg-recover, r=folkertdev Avoid `&raw` call recovery inside nested delimiters Fixes rust-lang/rust#157853 The `&raw <expr>` recovery is only valid for malformed raw refs directly in the call argument list. When it handled the nested array case, it tried to skip tokens until the call's ), reached the nested ], and could ICE in parse_token_tree. This PR scopes the call-argument recovery to the call's delimiter depth and makes the recovery loop stop before any closing delimiter or EOF.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
