The `wrong_self_convention` lint uses a `SelfKind` type to decide
whether a method has the right kind of "self" for its name, or whether
the kind of "self" it has makes its name confusable for a method in
a common trait. One possibility is `SelfKind::No`, which is supposed
to mean "No `self`".
Previously, SelfKind::No matched everything _except_ Self, including
references to Self. This patch changes it to match Self, &Self, &mut
Self, Box<Self>, and so on.
For example, this kind of method was allowed before:
```
impl S {
// Should trigger the lint, because
// "methods called `is_*` usually take `self` by reference or no `self`"
fn is_foo(&mut self) -> bool { todo!() }
}
```
But since SelfKind::No matched "&mut self", no lint was triggered
(see #8142).
With this patch, the code above now gives a lint as expected.
Fixes #8142
