Add suggestions for function pointers
- On compiler-error's suggestion of moving this lower down the stack,
along the path of `report_mismatched_types()`, which is used
by `rustc_hir_analysis` and `rustc_hir_typeck`.
- update ui tests, add test
- add suggestions for references to fn pointers
- modify `TypeErrCtxt::same_type_modulo_infer` to take `T: relate::Relate` instead of `Ty`

...
LL | let foo: fn() = foo;

| | help: consider casting to a fn pointer: `foo as fn()`
| expected due to this

= note: expected fn pointer `fn()`
found fn item `fn() {foo}`
= note: fn items are distinct from fn pointers
= note: functions with `#[target_feature]` can only be coerced to `unsafe` function pointers
