Rollup merge of #58526 - pmccarter:master, r=estebank 
Special suggestion for illegal unicode curly quote pairs

Fixes #58436

Did not end up expanding the error message span to include the full string literal since I figured the start of the token was the issue, while the help suggestion span would include up to the closing quotation mark.

The look ahead logic does not affect the reader position, not sure if that is an issue (if eg it should still continue to parse after the closing quote without erroring out).

Deduplicate mismatched delimiter errors

Delay unmatched delimiter errors until after the parser has run to deduplicate them when parsing and attempt recovering intelligently.

Second attempt at #54029, follow up to #53949. Fix #31528.

Suggestion moving types before associated types. 
This commit extends existing suggestions to move lifetimes before types
in generic arguments to also suggest moving types behind associated type
bindings.

b1f169fe7a Recover from parse errors in struct literal fields 
Attempt to recover from parse errors while parsing a struct's literal fields
by skipping tokens until a comma or the closing brace is found. This allows
errors in other fields to be reported.

Implement basic input validation for built-in attributes

Correct top-level shape (`#[attr]` vs `#[attr(...)]` vs `#[attr = ...]`) is enforced for built-in attributes, built-in attributes must also fit into the "meta-item" syntax (aka the "classic attribute syntax").

For some subset of attributes (found by crater run), errors are lowered to deprecation warnings.

NOTE: This PR previously included https://github.com/rust-lang/rust/pull/57367 as well.
