Improve `needless_lifetimes`

This PR makes the following improvements to `needless_lifetimes`.

* It fixes the following false negative, where `foo` is flagged but `bar` is not:
  ```rust
    fn foo<'a>(x: &'a u8, y: &'_ u8) {}

    fn bar<'a>(x: &'a u8, y: &'_ u8, z: &'_ u8) {}
  ```
* It flags more cases, generally. Previously, `needless_borrow` required *all* lifetimes to be used only once. With the changes, individual lifetimes are flagged for being used only once, even if not all lifetimes are.
* Finally, it tries to produce more clear error messages.

Rename some `OwnerId` fields.

spastorino noticed some silly expressions like `item_id.def_id.def_id`.

This commit renames several `def_id: OwnerId` fields as `owner_id`, so
those expressions become `item_id.owner_id.def_id`.

`item_id.owner_id.local_def_id` would be even clearer, but the use of
`def_id` for values of type `LocalDefId` is *very* widespread, so I left
that alone.

Fix `needless_borrow` false positive

The PR fixes the false positive exposed by `@BusyJay's` example in: https://github.com/rust-lang/rust-clippy/issues/9111#issuecomment-1277114280

The current approach is described in https://github.com/rust-lang/rust-clippy/pull/9674#issuecomment-1289294201 and https://github.com/rust-lang/rust-clippy/pull/9674#issuecomment-1292225232.

The original approach appears below.

---

The proposed fix is to flag only "simple" trait implementations involving references, a concept
that I introduce next.

Intuitively, a trait implementation is "simple" if all it does is dereference and apply the trait
implementation of a type named by a type parameter. `AsRef` provides a good example of a simple
implementation: https://doc.rust-lang.org/std/convert/trait.AsRef.html#impl-AsRef%3CU%3E-for-%26T

We can make this idea more precise as follows. Given a trait implementation, first determine
whether the implementation is "used defined." If so, then examine its nested obligations.
Consider the implementation simple if-and-only-if:
- there is at least one nested obligation for the same trait
- for each type `X` in the nested obligation's substitution, either `X` is the same as that of
  the original obligation's substitution, or the original type is `&X`

For example, the following implementation from `@BusyJay's` example is "complex" (i.e., not simple)
because it produces no nested obligations:

```rust
impl<'a> Extend<&'a u8> for A { ... }
```

On the other hand, the following slightly modified implementation is simple, because it produces
a nested obligation for `Extend<X>`:

```rust
impl<'a, X> Extend<&'a X> for A where A: Extend<X> { ... }
```

How does flagging only simple implementations help? One way of interpreting the false positive in
`@BusyJay's` example is that it separates a reference from a concrete type. Doing so turns a
successful type inference into a failing one. By flagging only simple implementations, we
separate references from type variables only, thereby eliminating this class of false positives.

Note that `Deref` is a special case, as the obligations generated for it already involve the
underlying type.

r? `@Jarcho` (Sorry to keep pinging you with `needless_borrow` stuff. But my impression is no one knows this code better than you.)
