Tweak E0599 to consolidate unsatisfied trait bound messages Fixes rust-lang#114430 r? @estebank

fix(parser): Disallow CR in frontmatter T-lang came back on the stabilization PR (rust-lang#148051) asking for CR to be disallowed to leave room for all stray CRs to be rejected in the future. At that point, the test can remain but the implementation can be removed. If that plan does not go through, we'll need to re-evaluate - whether this is more lint-like and should defer to the calling tool that is managing the frontmatter - how much Rust should treat the frontmatter as Rust and apply the same grammar restrictions of "no stray CR" (like raw string literals) Part of rust-lang#136889

Cleanup of `#[derive(Diagnostic)]` attribute parsers This PR does a lot of refactoring on the implementation of `#[derive(Diagnostic)]`. It should have no observable effect other than error messages for incorrect usage of the attributes. In general, I think the error messages got better. This PR can be reviewed commit by commit, each commit passes the tests. - [Convert parse_nested_meta to parse_args_with for #[diagnostic]](rust-lang@9e61014) Start parsing `#[diagnostic]` using `syn`'s `parse_args_with` function instead of `parse_nested_meta`. This improves error messages and prepares for the new syntax needed for rust-lang#151366 which cannot be parsed using `parse_args_with`. - [Convert parse_nested_meta to parse_args_with for #[subdiagnostic]](rust-lang@5d21a21) Same as above but for `#[subdiagnostic]` - [Remove unused no_span option](rust-lang@0bf3f5d) Removes the `no_span` option of `#[suggestion]`, which there were no tests for and which seems to have been unused. If needed again in the future, this can be re-added pretty easily, but I find that unlikely. - [Remove HasFieldMap trait in favour of passing FieldMap directly](rust-lang@2e8347a) Removes the `HasFieldMap` trait, because I don't really see the point of having a trait "has a field map" if we can just pass the fieldmap itself instead. r? @Kivooeo (Thanks for reviewing my PRs so far :3)

Overall result: ❌✅ regressions and improvements - please read the text below

Our benchmarks found a performance regression caused by this PR.
This might be an actual regression, but it can also be just noise.

Next Steps:

If the regression was expected or you think it can be justified,
please write a comment with sufficient written justification, and add
@rustbot label: +perf-regression-triaged to it, to mark the regression as triaged.
If you think that you know of a way to resolve the regression, try to create
a new PR with a fix for the regression.
If you do not understand the regression or you think that it is just noise,
you can ask the @rust-lang/wg-compiler-performance working group for help (members of this group
