Rollup merge of #63170 - matklad:cleanup-fields, r=petrochenkov 
cleanup StringReader fields

Rollup merge of #62550 - Centril:rest-patterns, r=petrochenkov 
Implement RFC 2707 + Parser recovery for range patterns

Implement https://github.com/rust-lang/rfcs/pull/2707.

- Add a new basic syntactic pattern form `ast::PatKind::Rest` (parsed as `..` or `DOTDOT`) and simplify `ast::PatKind::{Slice, Tuple, TupleStruct}` as a result.

- Lower `ast::PatKind::Rest` in combination with the aforementioned `PatKind` variants as well as `PatKind::Ident`. The HIR remains unchanged for now (may be advisable to make slight adjustments later).

- Refactor `parser.rs` wrt. parsing sequences and lists of things in the process.

- Add parser recovery for range patterns of form `X..`, `X..=`, `X...`, `..Y`, `..=Y`, and `...Y`.
   This should make it easy to actually support these patterns semantically later if we so desire.

Rollup merge of #62851 - matklad:unescape, r=petrochenkov 
move unescape module to rustc_lexer

It makes sense to keep the definition of escape sequences closer to the lexer itself, and it is also a bit of code that I would like to share with rust-analyzer.
