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.

395ee0b79f Introduce rustc_lexer 
The idea here is to make a reusable library out of the existing
rust-lexer, by separating out pure lexing and rustc-specific concerns,
like spans, error reporting an interning.

So, rustc_lexer operates directly on `&str`, produces simple tokens
which are a pair of type-tag and a bit of original text, and does not
report errors, instead storing them as flags on the token.

Fix #62660

If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE.

Rollup merge of #62329 - matklad:no-peeking, r=petrochenkov 
Remove support for 1-token lookahead from the lexer

`StringReader` maintained `peek_token` and `peek_span_src_raw` for look ahead.

`peek_token` was used only by rustdoc syntax coloring. After moving peeking logic into highlighter, I was able to remove `peek_token` from the lexer. I tried to use `iter::Peekable`, but that wasn't as pretty as I hoped, due to buffered fatal errors. So I went with hand-rolled peeking.

After that I've noticed that the only peeking behavior left was for raw tokens to test tt jointness. I've rewritten it in terms of trivia tokens, and not just spans.

After that it became possible to simplify the awkward constructor of the lexer, which could return `Err` if the first peeked token contained error.
