Suggest field typo through derefs
Take into account implicit dereferences when suggesting fields.
```
error[E0609]: no field `longname` on type `Arc<S>`
--> $DIR/suggest-field-through-deref.rs:10:15
|
LL | let _ = x.longname;
| ^^^^^^^^ help: a field with a similar name exists: `long_name`
```

When encountering a `Result<T, _>` or `Option<T>` where `T` has a field
that's being accessed, suggest calling `.unwrap()` to get to the field.
|
|
When encountering a type error caused by the use of `Self`, suggest
using the actual type name instead.
```

Fix #76086.
|
|
When encountering a type error involving a `Self` literal, point at the
self type of the enclosing `impl`.

Suggest publicly accessible paths for items in private mod:
When encountering a path in non-import situations that are not reachable
due to privacy constraints, search for any public re-exports that the
user could use instead.
Track whether an import suggestion is offering a re-export.
When encountering a path with private segments, mention if the item at
the final path segment is not publicly accessible at all.
Add item visibility metadata to privacy errors from imports:
On unreachable imports, record the item that was being imported in order
to suggest publicly available re-exports or to be explicit that the item
is not available publicly from any path.
In order to allow this, we add a mode to `resolve_path` that will not
add new privacy errors, nor return early if it encounters one. This way
we can get the `Res` corresponding to the final item in the import,
which is used in the privacy error machinery.

Better diagnostic message when trying to pattern match a tuple struct with a struct pattern.
|
|
Consider `tests/ui/const-generics/generic_const_exprs/issue-102768.stderr`,
the error message where it gives additional notes about where the associated
type is defined, and how the dead code lint doesn't have an article,
like in `tests/ui/lint/dead-code/issue-85255.stderr`. They don't have
articles, so it seems unnecessary to have one here.

The previous output was unintuitive to users.
