Fixes #10033.
Before this change, the lint would assume that removing the .to_string() in f(&x.to_string()) would be ok if x is of some type that implements Deref<Target = str> and f takes a &str.
This turns out to not actually be ok if the to_string call is some method that exists on x directly, which happens if it implements Display/ToString itself.
changelog: [unnecessary_to_owned]: only lint if the adjusted receiver type actually matches
