Point at parameter type on E0301

On "the parameter type `T` may not live long enough" error, point to the
parameter type suggesting lifetime bindings:

```
error[E0310]: the parameter type `T` may not live long enough
  --> $DIR/lifetime-doesnt-live-long-enough.rs:28:5
   |
27 | struct Foo<T> {
   |            - help: consider adding an explicit lifetime bound `T: 'static`...
28 |     foo: &'static T
   |     ^^^^^^^^^^^^^^^
   |
note: ...so that the reference type `&'static T` does not outlive the data it points at
  --> $DIR/lifetime-doesnt-live-long-enough.rs:28:5
   |
28 |     foo: &'static T
   |     ^^^^^^^^^^^^^^^
```

Fix #36700.
