Expand the primary span of E0277 when the immediate unmet bound is not what the user wrote:
```
error[E0277]: the trait bound `i32: Bar` is not satisfied
--> f100.rs:6:6
|
6 | <i32 as Foo>::foo();
| ^^^ the trait `Bar` is not implemented for `i32`, which is required by `i32: Foo`

help: this trait has no implementations, consider adding one
--> f100.rs:2:1
|
2 | trait Bar {}

--> f100.rs:3:14

| unsatisfied trait bound introduced here
```
Fix #40120.
