Esteban Küber b7fc1a7431 Add trait diff highlighting logic and use it in E0277
When a trait is not implemented for a type, but there *is* an `impl`
for another type or different trait params, we format the output to
use highlighting in the same way that E0308 does for types.

The logic accounts for 3 cases:
- When both the type and trait in the expected predicate and the candidate are different
- When only the types are different
- When only the trait generic params are different

For each case, we use slightly different formatting and wording.
