Fixed issue from #64447
Did two tiny fixes. One is a micro optimization since we know that max is going to be assigned a `usize`, we do not have to worry about a possible negative number.
The other issue that was fixed is that the max from the children isn't updated correctly. Now it will use `sub_result` instead of `primary` and will properly get the needed value.
Refactor librustc_errors::Handler API
This should be reviewed by-commit.
The last commit moves all fields into an inner struct behind a single lock; this is done to prevent possible deadlocks in a multi-threaded compiler, as well as inconsistent state observation.
Box `DiagnosticBuilder`.
It's a large type -- 176 bytes on 64-bit. And it's passed around and
returned from a lot of functions, including within `PResult`.
This commit boxes it, which reduces memory traffic. In particular,
`PResult` shrinks to 16 bytes in the best case; this reduces instruction
counts by up to 2% on various workloads. The commit touches a lot of
lines but it's almost all trivial plumbing changes.

This moves the two methods from the `EmitterWriter` impl to trait
default methods in the `Emitter` trait so that they can be re-used by
the `AnnotateSnippetEmitterWriter`.

librustc_errors: Extract sugg/subst handling into method
An initial refactoring before working on #61809.
This moves the whole block into a method so that it can be reused in the
annotate-snippet emitter. The method is already used in the new emitter, but
there's no UI tests with suggestions included in this PR.
A first look at some UI tests with suggestions showed that there's some
more work to do in [annotate-snippet-rs][annotate-snippet-rs] before the new output is closer to the
current one, so I opted to do that in a second step.
