Rollup merge of #126558 - jieyouxu:caller-chooses-ty, r=fmease 
hir_typeck: be more conservative in making "note caller chooses ty param" note

In https://github.com/rust-lang/rust/pull/122195 I added a "caller chooses ty for type param" note for when the return expression type a.k.a. found type does not match the expected return type.

#126547 found that this note was confusing when the found return type *contains* the expected type, e.g.

```rs
fn f<T>(t: &T) -> T {
    t
}
```

because the found return type `&T` will *always* be different from the expected return type `T`, so the note was needlessly redundant and confusing.

This PR addresses that by not making the note if the found return type contains the expected return type.

r? ``@fmease`` (since you reviewed the original PR)
